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.

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.

boards

- Verification of internal supplies

- Check of integrity of system

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).

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
