Contents ofCrate

Each crate includes:

ACR.

Pole mounting bracket with clamps if

ordered. If a substation mounting bracketwas ordered it will be attached to the outside

of the crate.

Six connectors if ordered (15TP or 30TP).

caulking gun.

The appropriate mounting kit.

ADVC (which will normally contain two

batteries unless arrangements have beenmade to ship batteries separately).

Control cable.

On receipt, the contents should be checked forshipping damage and the manufacturer

informed immediately if any is found.

Ensure that the ADVC is stored

indoors until installation on site. If

storage outdoors is unavoidable,

ensure that the ADVC is kept in an

upright position.

UnpackingProcedure

Tools required:

Wrecking bar to remove nails.

Four D shackles, two slings and crane with asafe working load of 200kg to lift the ACR.

Screw Driver or Battery Drill with 8mm

socket.

16mm Spanner or Socket.

Procedure:

1 Remove top of crate and lift out the control

cable. Store carefully in a clean dry place.

2 Unscrew and remove the four (4) screws

located on the wall of the crate. The

mounting bracket, mounting kit and the two

pieces of wood that the screws have just

been removed from are all secured together.

Lift the complete mounting bracket out of the

crate.

Take great care not to drop thebracket, which weighs nearly 30kg

(66lb), onto the ACR.

3 Fit D-shackles to the lifting points on the

ACR and lift it out of the crate and on to theground using the crane.

4 Tip the crate on to its side.

5 Remove the bolts securing the ADVC and

slide the unit from the crate.

The control cubicle weighs

approximately 40 kg (88lb).

Control CableConnection

When installing or testing the ACR it is

necessary to connect and disconnect the control

cable either from the ACR, the ADVC or both.

The control cable is plugged into the base of the

ACR and the other end into the ADVC at the

bottom, right-most socket on the Control and

Protection Enclosure (CAPE).

To do this successfully requires the correct

technique:

Power down the control cubicle by switchingoff all MCBs. This should be done whenever

connecting or disconnecting the control cable.

To connect: hold the plug by the long sides,

check orientation, gently locate it on the socket

and push firmly home. Check it has locked by

wriggling the plug. If the plug cannot be

pushed on with moderate force then it has not

been located properly. Heavy force is never

required.

To disconnect: (1) Hold the plug by the short

sides and grip hard to release the clips inside

the plug (not visible). (2) Wriggle the plug to

allow the clips to release. (3) Then pull the plug

out.

Never pull the plug out by the

cable.

Testing &Configuring

The tests can be carried out on site or in the

workshop as preferred.

Unpack the crate as above and put the HV

cables, boots and the control cable in a clean

safe place where they will not be damaged or

soiled. Make a temporary earth connection

between the ADVC and the ACR. 1mm² copper

wire is adequate for the purpose.

Figure 4: Handling the control cable plug


14/70


3-2

Raise the ACR using a crane or forklift in order

to safely gain access to the bottom of the ACR.

Unbolt the cover plate over the switch cable

entry module (SCEM) on the bottom of the ACR

and connect the ACR end of the control cable to

the SCEM.

Lower the ACR on to props so that the control

cable is not damaged by being caught between

the base of the ACR and the floor.

Then connect the ADVC end of the cable to the

socket at the lower right-hand corner of theCAPE located inside the ADVC cubicle. (See

Site Procedure, Step 14. on page 3-3.)

The LV auxiliary supply (if applicable) should be

connected as shown in Figure 5 (page 3-5).

‘Turn on the battery and auxiliary supply circuit

breakers at the bottom of the control cubicle and

carry out the following tests:

1. Manual trip and close of the ACR.

2. Insulation test the high voltage connections

to earth to check for shipping damage on the

high voltage side of the ACR.

3. Configure the protection settings.

4. Perform primary current injection as

required.

5. Perform secondary current injection (if

required by your Authority) using a Test and

Training Set (TTS).

6. Fit and test a radio or modem if required.

7. Attend to the battery using the care

instructions given in “Battery Care” on

page 10-2.

Connecting the batteries with

reverse polarity will cause damage

to the electronic systems.

An application note detailing workshop and field

test procedures is available. Contact your agent

or distributor.

Transport toSite

If the unpacking and testing was carried out in

the workshop then the ACR and ADVC must be

transported safely to site. It is important the

following steps are carried out:

Turn off all ADVC MCBs and disconnect all

auxiliary power supplies. Disconnect the

control cable from both ACR and ADVC and

put back the cover plate on the bottom of the

ACR.

Transport the ACR, ADVC and all parts in a

safe and secure manner to site.

SiteInstallation

If you are replacing a pole-top control

cubicle (PTCC) with an ADVC, the

following should be considered:

The ADVC mounting points will be different1.

The connection to the auxiliary supply enters

the cubicle at a different point.

The earth stud is in a different position.

Accessory cables may need extending.

Unlike the PTCC which required an

auxiliary power supply rating of 50VA, the

ADVC requires 100VA.

If the auxiliary supply is provided by an

external VT connected through the ACR,

there are limitations to the supply ratings of

equipment that customers may fit. In ADVC,General Specifications See “Radio/Modem

Power Supply Continuous Current” on

page 11-4.

Unlike the PTCC, the ADVC has locking

hinges on the door which prevent the door

from swinging or blowing shut. When you

open the door to 180°, it locks into that

position. To close the door, disengage the

hinge locks by raising the door slightly

before rotating it.

Tools Required Torque wrench and metric socket set,normal engineers tools.

Tools to prepare pole as required.

Crane or other lift for ACR and ADVC, four D

shackles and slings.

Parts Required(Not supplied bythemanufacturer)

Two 20mm galvanised or stainless steel

bolts with washers and nuts etc. to bolt the

ACR mounting bracket to power pole. See

Figure 6 (page 3-6). If the optional pole

clamps have been purchased this is not

required.

Mounting parts for the ADVC. Either 20mmsteel strapping or 10mm galvanised or

stainless steel bolts, nuts, etc.

Fixing hardware for the control cable. This is

a 27mm (1 1/16”) diameter sheathed conduit

and can be fixed to the pole with ties, straps,

P-clips or saddles.

Earth wire and lugs for the earthing scheme

and parts for LV mains auxiliary power

connection. See Figure 5 (page 3-5),Figure 10 (page 3-10) and Figure 11

(page 3-11).

1. An accessory mounting bracket can be purchased to allow the use of the same mounting holes as were used with themanufacturer’s PTCC. (Part No. 99800125)

20mm sealing cable entry glands to suit

auxiliary supply mains cables, 16mm sealing

cable entry glands to suit antenna or

communications cable as required.

Antenna, antenna feeder cable, and surge

arrester as required if a radio is fitted (unless

supplied by the manufacturer).

Site Procedure To erect and test the ACR and ADVC, carry outthe following steps. Mounting details are given in

Figure 6 (page 3-6):1. Transport to site and carry out testing prior to

erection as required.

2. Connect cable tails and surge arresters

before raising the ACR. See "Surge Arrester

Mounting and Terminating" - page 3-4 .

3. Ensure that the pole is of sufficient strengthto support the ACR. A structural engineer

may be needed to calculate the stresses

involved.

4. Securely mount the ACR mounting bracketon the power pole.

5. Lift the ACR into position and lower it onto

the mounting bracket so that it sits on themounting bracket. See Figure 6 (page 3-6)

and Figure 8 (page 3-8).

6. Bolt the ACR to the mounting bracket with

the four 12mm nuts and bolts provided.

Tighten to 50 Nm.

7. Complete the high voltage connections.

8. Unbolt the SCEM compartment cover plate

from the bottom of the ACR. Connect the

control cable to plug P1 on the SCEM

located inside the ACR. Then bolt up the

cover.

See Figure 4 (page 3-1) for the correct way

to connect/disconnect the control cable.

9. Run the control cable from the ACR down to

the ADVC.

10. If the ADVC is to be bolted to the pole, drill

the top hole and fit the bolt. If it is to be

strapped, feed the straps through the slots

on the upper and lower mounting brackets.

11. Lift the ADVC into position and bolt or strap it

to the power pole.

Note that the

ADVC mounts

have key holes as

shown here, so

that you can lift

the ADVC on to

the mounting bolt

and slide it into position.

When mounting the ADVC to a

wooden pole, use a spirit level to

ensure correct alignment, andminimise torque on the mounting

brackets.

12. Attach the control cable to the power pole

maintaining maximum available separation

from the main earth bond (at 200mm for

wood and concrete poles and 150mm for

steel poles). Ensure that there is enough

cable available at each end to permit

connection to the equipment.

13. Run the earth connections as described in

“Earthing” on page 3-4.

It is vital that the earthing scheme

is carried out as described.

14. Push the control cable from the ACR through

the base of the ADVC

and then connect it to the switchgear socket

on the CAPE.

15. For LV mains supply run auxiliary wiring as

shown in Figure 10 (page 3-10). Make the

connection inside the ADVC as shown in

Figure 5 (page 3-5).

16. For LV supply from a dedicated transformer

supplied by the utility, connect as shown in

Figure 11 (page 3-11).17. For Integrated supply from an external

transformer, connect as shown in Figure 11

(page 3-11). (See also “Auxiliary Power from

Integrated Transformer” on page 3-5.)

18. Power down the ADVC by switching off allMCB’s. Note that this should be done

whenever connecting or disconnecting the

control cable from the ADVC.

19. Fit the batteries if they are not already inplace.

Fitting the batteries with reverse

polarity will cause damage to the

electronic systems.

Surge ArresterMounting andTerminating

The ACR is type tested for Impulse Withstand

Voltages up to 125kV depending on the model.

See "Ratings and Specifications" - page 11-1

When there is a possibility that lightning ornetwork switching conditions may produce peak

voltages in excess of 70% of the Impulse

Withstand Voltage, the manufacturer

recommends the use of suitably rated surge

arresters connected to each terminal of the

ACR.

The arresters should be mounted on the

mounting brackets supplied by the manufacturer

and earthed as described in Figure 7 (page 3-7)

and Figure 9 (page 3-9).

If the arresters are not mounted

close to the ACR the protection they

provide is significantly reduced.

Lightning induced damage to the ACR or ADVC

voids the warranty if surge arresters are not

fitted.

Mounting brackets are provided for surgearresters on the ACR. This is illustrated in

Figure 6 (page 3-6) and Figure 8 (page 3-8).

The surge arresters can be mounted on top of

the brackets or clamped to the side of the

brackets using the holes provided. Top holes are

12mm diameter, side holes are 16mm diameter.In this way most types of surge arrester can beaccommodated.

The user should check that phase/phase andphase/earth clearance will be sufficient for their

particular surge arresters and line voltages. For

some types of side clamping surge arresters,the phase/earth clearance may be insufficient at

the centre phase on the pole side at higher

voltages. In this case the surge arrester can be

mounted on the side of the power pole or an

increased clearance ACR mounting bracket

fitted.

Connections from the surge arresters to thecable tails can be made by stripping off the

cable tail insulation and using a parallel or “T”

type clamp to make the connection to the cable

tail. The connection should be made far enough

up the tail so that phase/phase and phase/earth

clearances are maintained. It is good practice totape the joint using a bitumen or mastic tape, to

maintain the cabling system insulation.

Earthing Figure 10 (page 3-10) shows the earthingcommon to all installations.

This arrangement earths the ACR frame and the

surge arresters directly to earth through a main

earth bond consisting of a copper conductor of

70 sq. mm. Any surges will flow down this path.

Do not earth surge arresters by a

different path, doing this may

cause damage to the control

electronics or ACR. Also, any

antenna should be bonded to the

ACR or the main earth bond .

The control cubicle is connected to this main

earth bond by a tee-off. The control cubicle

electronics are internally protected from

potential differences which may occur between

the ACR frame and control cubicle frame whilst

surge currents are flowing down the main earth

bond . No other connections to earth from the

control cubicle are allowed since surge currents

will also flow in those paths. Follow this

arrangement on both conducting and insulating

power poles.

Keep the main earth bond physically separated

from the control cable, as they run down the

power pole, by the maximum spacing available

and at least 150mm.

LV AuxiliaryPower fromMains

Where LV mains are connected to the control

cubicle to provide auxiliary power, the

connection must connect the neutral of the LV

system to a tee-off from the main earth bond as

shown in Figure 10 (page 3-10). A low voltage

surge arrester must also be fitted from the LV

phase connection to this tee-off.

This connection scheme bonds the LV and HV

earths and so protects the primary insulation of

the auxiliary supply transformer in the control

cubicle when surge currents are flowing. Fit

additional LV surge arresters to all the other LV

phases (if they exist), to balance the supply for

other users connected to the LV system.

If local conditions or wiring rules prohibit

bonding the HV and LV systems in this way,

providing the auxiliary supply to the control

cubicle from the LV mains system is not

possible. Instead, use one of the alternative

arrangements detailed below.

LV AuxiliaryPower fromDedicatedUtilityTransformer

Figure 11 (page 3-11) shows wiring and earthing

if a dedicated transformer is supplied by the

utility. Note that this should not be used to

supply any other equipment without consulting

the manufacturer to ensure that no hazard is

caused to the control cubicle electronics.

Figure 11 (page 3-11) shows that the

transformer and any steelwork is earthed to the

switchgear tank and that one side of the

transformer secondary is earthed to the earth

stud on the equipment panel inside the control

cubicle.

Auxiliary Powerfrom IntegratedTransformer

The manufacturer can provide a dedicated

voltage transformer outside the ACR tank which

connects directly into the control electronics.

This is called an Integrated Auxiliary Supply .

An external transformer is mounted on the pole

as shown in Figure 11 (page 3-11) which also

shows suggested HV connections. The

secondary of the external transformer connects

into the SCEM on the underside of the ACR. To

connect the transformer secondary, remove the

SCEM compartment cover plate, pass the cable

which is pre-fitted with a cable gland through the

hole, secure the gland, connect the auxiliary

supply to the screw terminal block on the SCEM

and replace the compartment cover.

No additional earthing for Integrated Auxiliary

Supply is required in addition to the common

earthing shown in Figure 10 (page 3-10).

If the secondary of the VT is

earthed, electronics damage willoccur.

4 Communications and Accessories Installation

Ensure that the ADVC is switched

off before proceeding with the

installation of any accessory.

Radio Antenna Mount the antenna and run the antenna feed to

the ADVC or run external communications cableto the ADVC. The communication cable/radio

antenna, enters the cubicle via the 16mm hole

provided on the underside of the cubicle.

Figure 12: Cable Entry

Protection ofRadioEquipment

It is highly advisable to connect a gas discharge

type of surge arrester in the antenna feed to the

radio. Failure to do so will result in loss of radio

and control electronics protection which could

lead to complete electronic failure due to

lightning activity.A failure of this nature is not covered

by the products general warranty

arrangements.

A feed-through or bulkhead type arrester fitted

to the bottom of the control cubicle is ideal. If

fitted internally the surge arrester should be

earthed to an equipment panel mounting stud by

the shortest possible wire. Holes are provided

for a bulkhead surge arrester.

If a surge arrester is not fitted then the co-axial

earth screen should be earthed to the

equipment panel by the shortest possible wire.

The CustomerCompartment

At the top of the customer equipment

compartment is an accessory mounting rail for

installing customer equipment and accessories.

Equipment installed in this compartment can be

powered from the terminal block also mounted

on the rail.

Connecting to

the TerminalBlock

Insert a 4 mm screwdriver or similar tool into the

square hole above the appropriate wiring point

on the terminal block. Angle the head of the

screwdriver slightly upwards and push it in, then

lever it downwards.

This action will correctly position the wiring

clamp so that the stripped end of the cable can

be inserted. Release and remove the

screwdriver then gently tug the inserted cable to

ensure that it is firmly gripped.

Radio/ModemPower

The battery-backed power supply for a radio/

modem is provided on the terminal block as

described above1. See Figure 13 (page 4-2) for

the correct radio connection point.

The radio/modem power supply voltage is set by

the user in System Status

RADIO - S: Radio Supply 12 Volts page. This isa password protected parameter.

If the auxiliary power fails, battery power can be

conserved by automatically shutting down the

radio/modem power supply. The shutdown takes

place after the radio holdup time, set in System

Status RADIO - S: Radio Hold 60 min. page bythe user, has elapsed. If the Radio Hold time is

set to zero then the radio supply will not

shutdown, except under special circumstances

IOEX2Installation

The Input Output Expander (IOEX2) module

provides optically isolated inputs and voltagefree outputs to allow connection to external

devices. It is installed in a die cast, sealed

enclosure which is mounted on, and earthed via,

the DIN rail in the customer enclosure as shownin the following picture: (See Appendix B for

IOEX2 dimensions.)

The IOEX2 is suspended from the DIN rail by

two fittings on its rear surface:

To fit the IOEX2:

1 Holding the IOEX2 perpendicular, place theupper hooks of the hanging fittings over the

top edge of the DIN rail.

2 Push the IOEX2 firmly against the back

surface of the Customer compartment until

the lower end of the hanging fittings engagewith the bottom edge of the DIN rail.

3 Push the green/yellow earth terminal firmly

on to the DIN rail until it is engaged at both

the top and bottom.

4 Connect the IOEX2 supply using the cable

provided to the terminal block connection

point as shown in Figure 13 (page 4-2).

5 Connect the communications cable to Port Bon the CAPE. This RS 232 port is assigned

by default to the IOEX2. Excess cable

should be run through the cable duct.

CommunicationPorts

The ADVC has numerous communications ports

available to the user:

Not all ports are available for use at the same

time. The ports can be enabled/disabled via

WSOS.

Permanently available ports are:

IOEX communications

RS232 Four RS232 ports (A to D) are provided toconnect to conventional modems that providethe correct signalling for the communications

network used, e.g. optical fibre modem, or

telephone dial up modem, or RS232 radiomodem. All four ports have standard 9 pin D

male connectors and have the following pin

connections:

All RS-232 ports are not isolated from one

another or from the controller electronics. They

therefore can only be connected to devices

inside the controller that are powered by the

controller radio supply, including modems,

optical isolators, and radios.

Use of serial ports to connect

directly to other devices outside

the controller can cause damage

and void warranty. If connections

to other devices are required then isolation

interfaces MUST be used.

RS485 An RS485 port has been provided to enablehigher speed multi-drop connections that often

occur within substations. The RS-485 port is a

female RJ45 connector.

V23 FSK An in-built FSK modem provides half-duplexV23 signalling at 1200 bits per second. This

interface is primarily designed for use with voice

frequency radio systems and provides additional

signals for this purpose.

The V23 connector is RJ45:

The Push to Talk (PTT) signal is used to key up

a radio transmitter. PTT is implemented using a

Field Effect Transistor (FET) with an on

resistance of 3.3 ohm. When PTT is asserted

the transistor is turned on and connects the PTT

signal to 0V.

A busy signal can be provided by the radio to

indicate receive channel busy. High level is

+2.0V to +3.3V, and low level is 0V to +0.5V.The busy signal should be driven by an open

collector output or current limited to 10 mA.

Levels in excess of ±13V should

not be applied. The FET is rated for

a maximum of +32V and negative

voltages are not permitted.

Transmit and receive are unbalanced signals

relative to 0 volts and are not isolated. If a

DC level is imposed by the radio on the

transmit line then this should be less than

2.5 VDC.

If multiple ACRs are in use in a substation

application they can be connected to a singleradio using the 600ohm line isolator accessory

available from the manufacturer.

Ethernet The controller has a 10 base T Ethernet port.The port is a RJ45 female connector.

If the controller is connected to a

LAN or WAN then it is stronglyrecommended that:

1.Firewalls be used to limit user

access to the controller

2.Ethernet switches be used to

limit the volume of Ethernet data

reaching the controller's 10Base-T

port. (Use of Ethernet hubs is not

recommended.)

WindowsSwitchgearOperatingSystem(WSOS)

Windows Switchgear Operating System

(WSOS) is a software package available on a

PC that enables configuration, control and

monitoring of the controller.

The controller has its hatch port physically

connected to Port A via an interconnecting

cable. The default WSOS communications via

the port are 57600 baud, 8 bit, no parity, and 1

stop bit. WSOS communication set up

parameters are user configurable.

5 Testing Your Installation

The following sections give details of how the

ACR and ADVC, installed as described in

“Installation” on page 3-1, should be prepared

for operation.

Check that the installation and

external connections have been

carried out as described in this

manual and in accordance with

local regulations.

Ensure that earthing has been carried

out as described in “Earthing” on

page 3-4.

Check that no visible damage has occurred

during the installation.

Carry out any visual and electrical tests, such as

insulation and contact resistance, considerednecessary to prove that the installation is sound.

Powering Upthe ADVC

1 Turn on the battery circuit breaker,

The batteries are capable of

supplying very high currents.

Always turn off the battery circuit

breaker before connecting or

disconnecting the batteries in the cubicle.

Never leave flying leads connected to the

battery.

2 Turn on the auxiliary supply circuit breaker ifthe auxiliary supply is being provided by

either an LV mains or dedicated auxiliary

transformer.

3 Turn on the VT supply to cubicle circuit

breaker if the auxiliary supply is being

provided by an integrated transformer.

4 Powering up the ADVC with the ACR

connected will cause the ADVC to read data

from the ACR. This will take up to 60

seconds during which the message:

“READING - Do NOT disconnect

Switchgear” will flash at the top of thedisplay. The System OK LED on the OCP

should flash to indicate that the ADVC is

powered and functioning.

5 If the configuration file containing the

settings to be used in operation has notpreviously been loaded, it should be loaded

now using WSOS, or the settings should be

entered via the OCP.

The ACR and ADVC are now ready for

operation. Prior to energising the ACR, you

should perform the checks detailed below, to

confirm that the equipment is fully operational

and properly configured.If you are familiar with navigating

Operator Control Panel display

groups, proceed with the checks

described below. Otherwise, please

read the chapter, “Operator Control Panel” on

page 7-1 before continuing.

Battery For this and all subsequent tests youwill need to check settings on display

group pages (See “Display Groups” on

page 7-2.) You may also have to

check the Event Log (See “Event Log” on

page 8-1.)

1 In the System Status group, go to page

SWITCHGEAR STATUS - S2 Check the Battery status.

The battery may be in any one of four states:Normal; OFF; Low; High. At this point, the

battery state should be Normal with a

voltage within the range 23 to 29.5V.

- - - - - - - - - - SWITCHGEAR STATUS - - - - - - - - - SWork Tag OFFAux Supply Normal Battery Normal 27.5VSwitch Connected Switch Data Valid

5-2

Ensure the Aux Supply status is Normal. If

not, you cannot perform the remaining

battery checks at this stage.

3 Switch the battery circuit breaker off and

check that the battery status changes to

OFF. (Allow 3 - 5 seconds.)

4 Go to page EVENT LOG and check that

the bottom line of the display (the most

recent event) contains the Battery OFF

event.

When the battery status is Low Volts,

but the voltage is close to the normal

range lower limit, the battery will

charge up when the auxiliary supply is

turned on. If the voltage is very low, replace the

battery.

5 Switch the battery back on.

Connectionbetween theADVC and theACR


SWITCHGEAR STATUS - S2 Check the Switch status.

It may be in either of two states: Connected

or Disconnected. “Connected” is the normal

state. If Switch is “Disconnected”, check the

control cable at both ends. If the status

remains “Disconnected”, the cable may be

faulty.

3 Check that the Switch Data status is Valid.

In normal operation, if Switch status is

“Connected”, Switch Data will be “Valid”.

If the control cable has been unplugged

(Switch “Disconnected”, Switch Data

“Invalid”) then re-plugged (Switch status

“Connected”), the Switch Data status will

remain “Invalid” during the time taken to read

switch data from the SCEM, and a message

to that effect is displayed.

If Switch Data remains “Invalid”, check the

following:

Examine each end of the control cable,

checking for bent or broken pins and rectify if

found. Also check the socket at both the

SCEM and P1 in the ADVC for damage.

If the pins are OK, the cable itself may be

faulty1, therefore test the control cable for

continuity.

If Switch Data remains “Invalid”, check the

power supply to the SCEM by checking the

voltage on Pins 2 and 5 of the control cable.

The voltage should be approximately 36VDC

if the auxiliary supply is present or

approximately 26VDC if running on

batteries.

AuxiliarySupply


SWITCHGEAR STATUS - S2 Check the Aux Supply status.

The auxiliary supply may be in either of two

states: Normal or Fail.Ensure the battery status is Normal.

3 If using LV auxiliary supply, switch the

auxiliary supply off, OR if using integrated

auxiliary supply and the VT is energised,

switch off the VT supply to cubicle circuit

breaker. Check that the Aux Supply status

changes to Fail. (Allow 3 - 5 seconds.)

4 Check that the battery voltage has dropped

by approximately 2V, and that the battery

remains in Normal state.

If the battery voltage continues

dropping, and the battery state is

LOW, the batteries may be flat. If

the batteries are flat, replace

them.

5 Go to page

EVENT LOG and check that

the bottom line of the display (the most

recent event) contains the Aux Supply Off

event.

6 Switch the auxiliary supply back on.

event.

7 Return to page

SWITCHGEAR STATUS - S and change thesetting back to OFF.

TerminalDesignationand PhaseRotation

The power system phase assigned to each set

of bushings on the ACR must be correctly

indicated at the time of installation of the ADVC.

This process is called “setting the phasing”.

Setting the phasing affects all the displays,

events, etc., concerned with recloser terminals,

for example: voltage measurements, live/dead

terminal displays and maximum current events.

Normal/default phasing is A, B and C for

bushings I + X, II + XX and III + XXX. Normal/

default phase rotation is ABC.

If the phasing at the ACR and/or phase rotation

of the network are different from the default, you

must set the phasing and/or the phase rotation.

Phasing is set from the System Status page

TERMINAL DESIGNATION/ROTATION - S

1 Press the SELECT key to select the Phasing

field.

2 Press to change the setting.

3 Press the ENTER key when you have the

required phase combination. The controller

then orientates the currents and voltages to

match the selection.

4 In the Phasing field, select the phase

rotation - either ABC or ACB.


recent event) contains the Phasing order

event.

6 After the phasing has been set, you should

record the details on the label on the rear of

the control cubicle door (above the operator

panel) to indicate the relationship between

the bushings and phases.

Power FlowDirectionSetting

The ACR is a symmetrical device meaning that

either side can be connected to the power

source. However, the power source would

normally be connected to the side with the

CVTs. The bushings on that side are labelled l,

ll, and lll.

Consequently, after installation, the controller

must be configured to designate the source

side.

The power flow direction is configured on page

SYSTEM STATUS - PHASE VOLTAGE and POWERFLOW:

and may be either

Source I, Load X or Source X, Load I.

When changed, this reverses the power flow

direction but not the phasing.

Power flow direction setting is used to

determine:

Whether the source or load corresponds to

(I) or (X) on the voltage measurementdisplays.

Which direction is positive power flow for useon the kWh totals in the Maximum Weekly

Demand display and APGS.

Which is the source or load for Live Load

Blocking. Which is the source or load for Directional

Blocking/Protection.

Tripping andClosing

If system conditions allow, tripping or closing

can be carried out at this point.

1 Trip and close the ACR from the ADVC. See

“Operator Control Panel” on page 7-1. for

information on the Trip and Close controls.

2 Tripping and closing should cause the LED

on the appropriate TRIP/CLOSE button to

illuminate which should agree with the

position of the pointer on the ACR.

Enable/DisableSwitches

For each of the CLOSE and TRIP keys in turn, test

ENABLE and DISABLE by:

1 Disable either mechanism e.g. CLOSE.

When the CLOSE or TRIP mechanism

is disabled, the message

recent event) contains the Close Coil Isolate

event. (For the same test of the TRIP

mechanism the Event Log should display

Trip Coil Isolate.)

3 With both mechanisms disabled, check that

pressing each of the CLOSE and TRIP keys

is ineffective.

4 Enable both CLOSE and TRIP mechanisms.

MechanicalTrip

1 Use a hook stick to manually trip the ACR

via the manual trip lever.

2 Go to page EVENT LOG and check thatthe bottom line of the display (the mostrecent event) contains the Mechanical Trip

event.

SecondaryInjectionTesting

If secondary injection testing is required to test

protection settings but operation of the ACR is

not possible, secondary injection can be

performed with a suitable current injection set

with the Test and Training Set (TTS) in

standalone mode connected to the ADVC, andthe ACR disconnected.

If tripping and closing of the ACR is possible and

preferred, perform secondary injection testing

with the TTS in parallel mode.

Any secondary injection must use a

frequency which corresponds to the

frequency set in the controller.

PrimaryInjectionTesting

If the ACR can be isolated from the network,

primary injection testing can be performed if

required.

Power FlowDirectionTesting

This test is to ensure that the source and load

designations are correct.

This test is valid only if the ACR is

being supplied from a single sourceand can be energised before closing.

Since either side of the recloser can be

connected to the power source, the controller

must be configured to designate the source

side.

The power flow direction is configured in System

Status on the PHASE VOLTAGE and POWERFLOW - S page.

If the I -side bushings are connected to the

source, the setting should be Source I,

Load X.1 Display the page and check the Source,

Load configuration.

The correct power flow setting can be confirmed

by energising the ACR while it is open.

2 With the recloser energized but still open, in

System Measurement, go to SOURCESIDE VOLTAGES - M

3 Check the source side voltages - eitherphase to earth (ground) or phase to phase

e.g.


LIVE/DEAD INDICATION - S

5 If Steps 3 and 4 indicate an incorrect power

flow setting, return to Step 1, change the

setting and repeat Steps 2-4.

6 Control Electronics Operation

The ADVC is purposely designed for outdoor

pole mounted operation. The cubicle is vented

and insulated to minimise internal temperature

variation and maximise battery life.

Figure 24 (page B-2) shows the cubicle’s

dimensions.

Sealing &CondensationAll cubicle vents are screened against verminentry and the cubicle door is sealed with

replaceable foam tape.

Complete sealing against water entry under all

conditions is not expected e.g. during operation

in the rain. Instead, the design is such that if any

water does enter, it will run out of the bottom

without affecting the electrical or electronic

parts. The extensive use of stainless steel and

other corrosion proof materials ensures that the

presence of moisture has no detrimental effects.

Condensation can be expected to form undersome atmospheric conditions such as tropical

storms. However, condensation will be on metal

surfaces where it is of no consequence. The

water runs out in the same way as any other

water entering the cubicle. Condensation will

run out of the bottom or be dried by ventilation

and self heating.

All electronic modules are fully sealed and have

self heating.

AuxiliaryPower Source

The auxiliary supply is used to maintain charge

on the sealed lead-acid batteries that provide

standby power when auxiliary power is lost. The

controller monitors the status of both the

auxiliary and battery supplies.

A low power mode is activated when the

batteries are nearly exhausted due to loss of the

auxiliary supply. This mode minimises power

consumption while still maintaining basic

functionality.

Controller The controller comprises 3 modules (SeeFigure 18 (page 6-3):

Power supply unit (PSU)

Control and protection enclosure (CAPE)

Basic Display Unit (BDU).

The ADVC block diagram is given in Figure 19

(page 6-4).

PSU Module The PSU module supplies power to the CAPE,and to the customer compartment. The PSU

module:

connects to the batteries

controls the supply from external auxiliary

sources

filters these supplies and manages the

battery power level.

It also performs battery testing and has a non-

volatile, real time clock. A general purpose

power outlet is available as an optional extra

(country customizable). The incoming power is

protected and isolated by a circuit breaker. The

supply from the batteries is protected and

isolated by a circuit breaker.

The electronic components are contained inside

a housing that provides environmental

protection, sealing and EMI shielding. The

power outlet, circuit breakers and switches are

easily accessible when the ADVC door is

opened. The batteries are located and retained

on the exterior top of the PSU module.

CAPE Module The CAPE Module comprises two printed circuitboard assemblies and the trip and close

capacitors housed in a die-cast aluminium

enclosure. The two printed circuit board

assemblies are:

PCOM: Protection and Communication

Module

SWGM: Switchgear Module

The CAPE enclosure is manufactured from

pressure die-cast aluminium. The front surface

with the user and switchgear connectors, andthe rear surface, are gasketed to provide an

IP65 Degree of Protection. The enclosure also

provides EMC shielding for the CAPE

electronics.

The PCOM is the heart of the ADVC and

includes the data acquisition hardware

(including a powerful Digital Signal Processor)

and communications hardware (Ethernet,

RS232, RS485 and V23). All user-interface,

measurement, protection, communication andcontrol functionality is provided by software

running on the PCOM.

The SWGM contains the switchgear interface

hardware, SCEM interface hardware, EMCprotection and filtering devices and high voltage

inverters for the trip and close capacitors.

Event Log

8-1

8 Event Log

When the status of the control electronics or

switchgear changes, events are generated

which are recorded in an Event Log for display

to the operator. Examples of such events are

‘Load Supply On’ or ‘Lockout’.

Events are viewed on the Event Log pages and

can also be up-loaded and viewed with the

Windows Switchgear Operating System.

The event log display looks like this:

Events are dated, time stamped, and displayed

in the order in which they occurred.

The key scrolls the display downward toshow older events, the key scrolls thedisplay upward to show more recent events.

Pressing the key removes the title of thedisplay to make more room for events. The title

will only be restored when the event log is

selected again from the top level menu.

Display

Updating

The event log display will update automatically

with new events, provided the most recent eventis on the bottom line of the screen. When new

events occur they are entered at the bottom of

the screen and the older events are scrolled up.

Event LogFormat

Each event occupies one line of the event log.

The standard display contains (reading from the

left):

the date of the event,

the time of the event, and

the event description.

Additional information e.g. event source isrecorded and can be made visible if you press

the ALT key while the event is displayed.

Using the ALTKey

If the Alt key is pressed whilst the event log is on

display, the date and time details may bereplaced with extra information that includes, at

far left, the event source and followed by, if

applicable, additional event details. Examples of

source codes are:

Additional event details are available where the

combination of the source plus event descriptionalone will not precisely identify the event e.g.

protection events or events sourced to WSOS.

Examples of additional details are:

the protection group

curve

trip number

port identification

protocol.

Typical EventLog Displays

A typical sequence of events for a phase/phase

fault, which had instantaneous protection on the

first trip and inverse time protection on the

second trip, with two trips to lockout might be as

shown in Figure 21 (page 8-2).

However, if the fault was cleared after the first

trip has occurred, the controller will generate a

‘Sequence Reset’ event once the Sequence

Reset Time has expired, as shown in Figure 22(page 8-2).

Power System Measurements

9-1

9 Power System Measurements

The current transformer (CT) signals and

voltage screen (CVT) signals from the recloser

are digitised by the ADVC and used to provide a

variety of data for the operator.

The ADVC measures up to 10 power system

components:

A, B, C, phase and spill currents, phase-earth voltage on all six terminals.

The ADVC uses the above measurements to

derive many system measurements including:

frequency,

phase to phase voltages,

total and per phase power (kW, kVA, kVAR),

total and per phase power factor,

harmonics,

earth current, and

sequence components.

In addition the ADVC also measures severalinternal values such as:

CAPE temperature,

switchgear temperature1

auxiliary voltage,

battery voltage.

Power SystemFrequency

The controller must be set for the correct power

system frequency – either 50 or 60 Hz.

This is set on page

Maintenance

10-1

10 Maintenance

Maintenance can be carried out using standard

electricians’ and mechanics’ tools.

Be careful to ensure that if working

on the ADVC with the door open in

heavy rain, water does not enter

the circuit breakers or general

power outlet.

ACRMaintenance

No user maintenance of the ACR mechanism isrequired.

The ACR should be returned to the

manufacturer for refurbishment if the

mechanical duty or breaking duty is exceeded.

This is checked by examining the remaining

contact life on the Operator Control Panel.

When the remaining contact life in any phase

approaches zero, the ACR has reached the end

of its life and must be replaced.

A warning is displayed in the event logwhen the remaining contact life reaches

20%.

Every five years the bushing boots should be

checked, cleaned if necessary and the pointer

checked to ensure it is free from mechanical

obstructions. In areas of high atmospheric

pollution more frequent cleaning may be

appropriate.

ADVCMaintenance

Maintenance of the ADVC is required every fiveyears. The manufacturer recommends the workdescribed below.

Cleaning Check for excessive dirt on the cubicle,particularly the roof, and clean off.

Ensure that the mesh covering the air vents and

the water drainage holes in the base are clean.

BatteryReplacement

Battery replacement is recommended after a

period of five years. See "Battery Care" -

page 10-2 .

The procedure is:

1 Turn off the battery circuit breaker.

2 Unplug batteries and replace with new

batteries.

Ensure that battery polarity is

correct.

3 Turn on the battery circuit breaker and

ensure that “Battery Normal status”, is

restored on the page

SYSTEM STATUS-SWITCHGEAR STATUS

Battery HeaterAccessory

Where the battery heater accessory has been

fitted the following procedure should be

followed:

1 Turn off the battery circuit breaker.

2 Disconnect batteries and heater.

3 Open straps and remove heater box.The battery heater box is heavy

and should be removed with

caution. Do not tilt the heater box.

Battery heater failure will be reported in

the Event Log.

Door Seal Check the door sealing rubber for perishing orundue hardening. If necessary renew the seal.

Battery Care The battery is predicted to provide goodperformance for the recommended five year

service period. This is based on the battery

manufacturer's data. No battery warranty isgiven by the manufacturer of the ADVC.

Once in service, batteries need little care.

Procedures for storage and other contingencies

are as follows:

Batteries should be stored at a temperature

of between 0°C to 30°C (32°F to 86°F) and

cycled every six months. Batteries should be

stored for a maximum of one year.

Batteries should be cycled prior to putting

into service if they have not been cycled

within three months. When shipped by the

manufacturer the batteries will have been

cycled within the previous 30 days.

If the batteries become exhausted in service

and are left for more than two weeks without

auxiliary supply being restored to the ADVC

they should be taken out, cycled and have

their capacity checked before being returned

to service.

To cycle a battery, discharge with a 10 Ohm 15Watt resistor to a terminal voltage of 10V. Next,

recharge it with a voltage regulated DC supply

set to 13.8V. A 3A current limited supply is

appropriate.

Battery type, either standard or extended

temperature, is given in Appendix A (page A-1).

More information on the battery care is available

from the battery manufacturer.

These batteries are capable of

supplying very high currents.

Always turn off the battery circuit

breaker before connecting or

disconnecting the batteries in the cubicle.

Never leave flying leads connected to the

battery.
