Withdrawable Switchgear Module COMPASS 110 to 170 kV

Compact air-insulated switchgear fully assembled and tested in factory, for rapid energizing in 24 hours

A COMPASS Module includes all the high voltage functions of a switchgear bay in just one module. It is suited both for indoor and outdoor installations.
The transport of the module can be conducted with ordinary vehicles, it arrives pre-fabricated and pre-tested on site ready to energize in 24 hours, thus allowing a faster commissioning time of the whole substation. A COMPASS module requires up to 50% less space compared with a conventional air-insulated switchgear bay.

Each Compass can include:
- Circuit-breaker
- Disconnectors with their own motor/manual drive
- Earthing switches with their own motor/manual drive
- Current transformers
- Voltage transformers
- Surge arresters
- Spring or digital motor drive
- Conventional or digital control cabinet


  • Integration of renewable power to the grid
  • Railway substations
  • Substation extensions or bay replacements
  • Digital substations

Why ABB?

  • Long experience and large installed base with COMPASS, 2000 bays installed since 1996
  • COMPASS can be serviced and inspected easily by lowering a section of the module which includes circuit breaker, current transformer and the mobile contact of the disconnector. The necessary operations are carried out on a ground level so safety and efficiency are ensured. 
  • Global service organization, local everywhere
