COMPASS is the result of the multifunctional modular approach applied to air insulated switchgears. It combines:
- Circuit breaker.
- Air disconnectors with clearly visible separation of contacts.
- Earthing blades, manual or motorized.
- Current transformers, voltage transformers and surge arresters mounted on brackets attached to the supporting structure.
The advantages of COMPASS are:
- Modularity and full-integration made available for users that are attached to air insulation.
- Easy maintenance thanks to possibility to lower the frame without unclamping the module.
- Cheap and easy building of H-scheme substations by using the NABLA bus bar system.

PASS – Plug And Switch System Gas density control
Density monitor
Since the dielectrical strenght of
the switchgear and the breaking
capacity of the SF6 circuit-
breaker depend on the density
of the SF6 gas, a gas density
relay is installed to control gas
density and detect leakage.

PASS – Plug And Switch System Fast earthing Switch
PASS M0 can be equipped on
request with the fast earthing
switch
Fast Earthing Switch SBT/R 145-
170 kV consists of three separate
poles driven by mechanical drive
BES 7. Energy needed for fast
closing operation of earthing switch
is stored in two springs.
The SBT/R can carry out two closing
operations at 40 kA - 100kA peak,
without any reduction of insulation
level. Subsequentely maintenance is
needed and consists in substitution
of mobile and fixed contacts and
SF6 gas replacement for gas
compartment where FES is
allocated.

performed.
- Basic version integrates sensors for CB (event log register CB speed,
profile, time), temperature and SF6 pressure; historic data is recorded and
accessible by downloading the event log.
- LCCs can be easily an quickly reconfigured acting only on software
- Automatic operations
- Interlocking
- I/O signals
- Managed data or drives expandable simply by adding boards.

Contrarily to electromechanical
relays, malfunctioning is detected
real time (e.g. a malfunctioning
board).
Failures are signalled live and
recorded with reference to the date.
The system continuously records:
- Charger functionality
- Correct functioning of all the I/O
boards
- Verification of internal supplies
- Check of integrity of system
control logic
- Verification of the inverter’s
functionality.

Logs
Two performance logs are available anytime:
- Travel curve log that allows to verify a large number of
motor control parameters (e.g. motor phases current,
torque profile, speed profile, position profile, flux and
torque currents).
- System log that allows to check (with date and time stamp)
all the events occurred in the system, e.g.:
i. Each attempted maneuvers and the status (performed
/ failed)
ii. System malfunctioning detected by diagnostic - i.e.
warning or failure (e.g. position not communicated by
the encoder, motor not connected, main/backup
supply not functioning, incorrect board in the slot etc.)
iii. Service access to the system (e.g. to upload a new
configuration).

T – PASS (TIP for Rural Electrification) Features & Benefits
Other solutions to protect the TIP:
No protection: risk for the TIP in case of short-circuit on the line
& vice-versa
HV fuse in the bushing: high risk of unavailability (long
outages), maintenance on the full product needed for any short
circuit on the line (in a remote location, by skilled technicians)
External HV fuse(up to 145kV): medium risk of unavailability,
substitution of the fuse needed for any short-circuit on the line.
Substation breakers: if the TIP is installed in a substation
Other type of breakers: COMPASS, DTB, LTB, GIS, etc.
