Switchgear Service

When a board has tripped, failed or been damaged, service work has to be methodical. We fault-find, repair or replace, then re-commission and prove the board before it carries load again.

Where components are obsolete we identify current equivalents so the board can stay in service instead of being replaced wholesale.

Fault finding on power, control and protection circuits
Breaker, relay and protection setting checks and adjustment
Component replacement including contactors, relays and meters
Changeover and interlock sequence testing
