Withdrawable Switchgear Module COMPASS 110 - 170 kV

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

• 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
