MOTOR AND OVERCURRENTPROTECTION RELAYThe MiCOM P22x protection relay range is designed for motor protection applications. A complete set of protectionfunctions is performed on the measurement of current,

voltage* and temperature. In addition to these basicfunctions, the relay carries out a large number of other functions that enable it to protect and run the motor moreeffectively.

The reliability of the system is further enhanced via checkson bus voltage prior to start-up, supervision of trip-circuitwiring continuity and protection against circuit-breaker failure.

The MiCOM P22x protection relay range is particularlyadapted to Oil refinery, chemical plant, metallurgy, glassand cement manufacturing, paper mills, electrical andmechanical engineering, food production, mining etc. It isalso suitable for water treatment and in pumping stationsas well as in steam power plants.

On top of that high inertia loads and anti-backspinprotection ensures that the rotor stops before the motor can be re-started.

For motors whose current supply contains a considerabledegree of distortion, the relay provides a true RMS basethermal image allowing efficient protection againstoverload phenomena due to the presence of harmoniccomponents. The addition of power measurement* andenergy metering*, and the presence of analogue outputs(current loop) make the MiCOM P22x protection relayrange a highly competitive and effective equipment interms of protection.

APPLICATION

The MiCOM P22x protection relay range performs andoffers a numerous functions in a compact design:

> Protection

> Monitoring

> Diagnosis

> Fault analysis tools

> Aid to maintenance

Compact and "Plug and play" made, the P22x protectionrelay range supply essential functions for industryapplications, where the following requirements must beachieved:

> Small and medium motors

> High inertia> Compact case model

> Easy to use

> Low cost







MAIN FUNCTIONS

Protection functions are autonomous and can beindividually configured or disabled to suit a particular application.

PROTECTION FUNCTIONS

Short-cir cuit (50/51)

A phase over-current element allows for the detection of faults between phases. In addition to this short-circuitthreshold, a time-delayed signal and an instantaneoussignal are available to provide better selectivity.

Earth fault (50N/51N)

Two elements are available. Each threshold hasinstantaneous and delayed signal at its disposal. Theadjustment range for earth current threshold varies from0.002 to 1 Ion, allowing maximum sensitivity for earth faultdetection. The relay's earth current input can be wired to acore balanced CT or to the summation of the three-phaseCTs.

CB failure (50BF)

The CB failure on fault will be detected very quickly by theP225 relay, which will then either send a new local trippingsignal or act directly on the immediately upstream CB. Byspeeding up the time taken to clear the fault in the case of CB failure, the P225 relay help maintain the stability of thenetwork and the reliability of the protection system.

Limitation of the number of starts, time betweenstarts (66)

The number of motor start-ups can be limited. The P22xrelay can discriminate between a warm and a cold motor,making it possible to optimise the number of start-upsallocated to a particular motor over a given period of time.Setting a minimum delay between two start-ups avoidsexposing the motor and its start-up system to over-largeresultant stresses.

Loss of load (37)

A timed minimum phase current threshold detects loss of load, caused by shaft rupture or the unpriming of a pump.This function can be deactivated during the start-up phaseso that the motor can gradually increase its load.

Unbalance, loss of phase and single phasing(46)

Two over-current elements based on the negativesequence component of current are available. One isassociated with an IDMT characteristic, while the other hasa definite time characteristic. The two elements make it

possible to differentiate between a short or low amplitudeunbalance and a more marked phenomenon such as lossof phase or single phasing.

Thermal overload (49) - True RMS base

The thermal image of the MiCOM P22x relay allows for simultaneous protection of the rotor and stator windings of the motor, whatever the operating conditions of themachine, under and overload operating conditions, duringstart-up, with rotor locked or with the motor off.

Classic I2t thermal images afford protection to stator windings but do not take account of overheating in therotor during a current unbalance. Similarly, the presence of harmonic current components causes additionaloverheating of the stator windings. In order to take this

overheating properly into account, the P22x relayseparates the negative sequence current and reconstitutesit with the true RMS value of the stator currents absorbedby the motor.

The result is better protection against overloads and hencea marked decrease in the risk of motor damage. An alarmthreshold, tripping threshold and thermal threshold, beyondwhich the motor cannot be restarted, are available.

As an option, RTDs can be connected to the MiCOM P220relay to monitor the motor's temperature. For each of theRTD channels, two temperature thresholds with individual

time-delay settings are available. It is therefore possible tomonitor stator windings separately, as well as the spinbearings of the motor and the load involved. If the motor isequipped with thermistors, the P220 relay monitor temperature via its three thermistor inputs.

Undervoltage (27) / Overvoltage (59) / Re-acceleration authorisation (27 LV)

If voltage supply drops or is lost completely, a phase tophase under voltage threshold causes the motor to stop.This function on P225 relay can be selectively put into or out of operation during the motor start-up phase. An over-voltage threshold protects against over-voltage and alsogives warning of ageing insulators.

The relay can detect voltage sag via its voltage input.

Depending on the duration of the voltage sag, the P225relay can authorise a re-acceleration of the motor when fullvoltage returns or, on the other hand, stop the motor to letthe motors most critical to the process re-accelerate.

Latching of output relays (86)

The trip order can be maintained to avoid the risk of re-starting on an electrical, mechanical or thermal fault.

Excessive start time (48) / Locked rotor whilerunning or at start-up (51LR)

Whether the motor is unloaded or coupled to a heavy load,this function monitors the duration of the motor start-upphase.

The choice of the motor's start-up detection criteria makes

it possible to use this function, whatever the motor's start-up mode: direct on line, star-delta, auto-transformer,resistor insertion, etc. During normal motor operation, anover-current threshold detects rotor stalling.

Locked rotor while running or at start-up (51S)

During motor start-up, a locked rotor is detected with thehelp of a speed switch input on P225 relay.

Anti -backspin

If a motor with a high inertia load, for example a fan, isstopped, the shaft continues to rotate for some time beforethe rotor stops completely. If the motor is switched back onwhile the rotor is still turning, something akin to a falsecoupling may occur, causing mechanical damage such as

broken fan blades. Setting a minimum time-lapse betweenstopping the motor and re-starting it can eliminate the riskof such problems.

Presence of bus voltage prior to start-up

Prior to starting the motor, the P225 relay check thatvoltage levels are sufficiently high before authorising thestart-up sequence.

Emergency start-up

When required by safety conditions or by the process, alogical input of the P22x relay can be used to allow motor start-up. All start-up restrictions will then be inhibited andthe thermal image function will be disabled.




CONTROL FUNCTIONS

Independent protection setting groups

By virtue of its two setting groups, the MiCOM P22x relayallows for the protection of dual-speed motors as well asmotors operating under environmental or operationalconditions, which are not constant over time. A change of

setting group can be useful following a change in sourceimpedance. The result is improved selectivity.

Programmable scheme logic (4 basic equations)

MiCOM P22x can achieve up to 4 AND logical gates linkedto time delays, by combining internal and externalinformation with the protection relay. The user can alsocreate OR gates by individually programming each outputrelay. The logical gates help make economies on externalrelaying and make the relay interactive with the process.

Trip circuit supervisionSupervision of wiring continuity in the trip circuit makes thesystem more reliable.

The relay can detect a break in the circuit, whether the CBis on or off.

CB monitoring

Preventive CB maintenance is provided by monitoringsummated contact breaking duty, the number of switchingoperations and the opening time. If a pre-set threshold isexceeded, the P225 relay will generate an alarm signal.

External trips

The P22x relay accepts external binary signals, which canbe used to give a trip or alarm signal, or which may simplybe treated as binary information to be passed up throughthe relay to a remote control system.

Shape of start-up current and voltage

The MiCOM P22x relay records the envelope of both start-up current and voltage signals with a resolution of onesample for every 5 periods. This recording can beuploaded to a PC via the communication network or via theRS232 port on the front plate. It is very helpful to be able tovisualise these curves during commissioning and thisfunction of the MiCOM P22x avoids the need for a plotter.

Analogue outputs

Two optional analogue outputs are available.

Some information and measurements such as power (P225), energy (P225) and temperature values, etc., canbe fed through a current loop to a PLC.

Trip cause statistics

The MiCOM P22x relay provides the user with tripstatistics for every protection function. The user can thuskeep track of the number of trips, which have taken placeas well as their origin.

MEASUREMENTS AND RECORDINGFACILITIES

Measurements

The MiCOM P22x relay constantly measures a largeamount of electrical data, such as:

> Phase current magnitude in true RMS value: IA,IB, IC

> Neutral current magnitude in true RMS value: IN

> Positive sequence current I1

> Negative sequence current I2

> Zero sequence current Io

> Unbalance ratio I1/I2

> Frequency • Peak current value

> Phase-to-phase voltage in true RMS value*

> Active and reactive power W and VAR*

> Active and reactive energies Wh and VARh*

> Power factor* To provide the user with more

accurate information on the motor's status andavailability, the P22x relay keeps track of:

> Thermal status of the motor

> Load value as a % of full load current

> Time to thermal trip

> Temperature of each RTD*

> Hottest RTD*

> Authorised start number

> Time before another start-up authorisation

> Last start current magnitude

> Last start time value

> Number of starts and emergency starts

> Total motor running hours

Event records

The last 75 status changes are recorded in a non-volatilememory. This covers all status changes to logic inputs andoutputs, modifications to one or more parameters, alarmsignals or the operation of one of the output contacts.Events are logged every 1 ms.

Fault records

The P22x relay records the last 5 faults. The informationprovided in the fault record includes:

> Fault number

> Date and time

> Active setting group

> Faulty phase or phases

> Function that gave the trip

> Magnitude of the value that gave rise to the tripcommand

> Values of the phases and earth currents andvoltage*.

Disturbance records

5 resp. 8 disturbance records, of 2.5 seconds each, can bestored,. Disturbance record can be uploaded via thecommunication network (RS485/optical fibre*) or locally(RS232).

* Available on some models.




USER INTERFACE

Front plate and menus

All the relay's parameters, protection functions, logiccontrols, communication, LEDs, inputs and outputs, can beprogrammed and modified by pushbuttons located on thefront panel. An alphanumeric, highlighted, 32-character

LCD screen displays all the relay's data (settings,measurements, etc.). The menus are designed so that theuser can move around them easily, without confusion. Theuser will soon be at ease with the Human-MachineInterface.

Dedicated and programmable LEDs

4 LEDs show the relay's status (Trip, Alarm, Equipmentfault and Healthy). MiCOM P22x relay offers freeprogramming of 4 LEDs. Each LED can be assigned toone or more functions or logic states and then limits theneed for external signal lights.

Push-buttons and function keys

The operator menu is accessed via 7 touch-sensitivebuttons.

Local and remote communication

The MiCOM P220/P225 relays are equipped with a RS485port on its rear plate, which enables them to communicatevia MODBUSTM, Courier* or IEC 60870-5-103.

It is thus possible to transmit adjustment values,measurement data, alarm signals and all other recordingsto the Substation Control System or to a SCADA.

The operator via the user interface can adjustcommunication parameters. Communication failure doesnot affect MiCOM relays' protective functions.

SOFTWARE SUPPORT

MiCOM S1 software makes it possible to pre-set allMiCOM P22x relay parameters from a PC. The relay isthen accessed via the RS232 port on the front panel.

MiCOM S1 software is fully compatible with WindowsTM

(95, 98, NT, 2000, XP), and can download relay settings,

pull up current relay settings and upload measurementvalues, diagnostic data, fault records, disturbance records,start-up current and voltage shapes and event loggingdata.

Emergency start-up (P225)When required by safety conditions or by the process,logical input of the P22x relay can be used to allow motor start-up. All start-up restrictions will then be inhibited andthe thermal image function will be disabled.

CB failure (50BF) (P225)

Current threshold I< BF:10 … 100% In (steps 10% In)

Time-delay tBF: 0,03 … 10.00 sThe CB failure on fault will be detected very quickly by the

P225 relay, which will then either send a new local trippingsignal or act directly on the immediately upstream CB.By speeding up the time taken to clear the fault in the caseof CB failure, the P225 relay help maintain the stability of the network and the reliability of the protection system.
