Case study

Replace generator circuit breaker insulators and recondition for service

600MWpower station returned to safe, efficient operation

The challenge

A 600MW power station encountered a severe issue when its generator circuit breaker (GCB) enclosure became filled with rainwater during a series of storms.

The water caused a flashover, extensively damaging the resin insulators, leaving the equipment unsafe, unserviceable and in urgent need of repair.

Our solution

We quickly drained the water and thoroughly cleaned the enclosure to assess the damage. Given the prolonged exposure to water, we recommended replacing all support insulators.

The circuit breaker and disconnector were removed and repaired and HV testing was conducted to ensure full functionality.

The result

The circuit breaker was meticulously rebuilt and underwent rigorous testing to ensure full functionality.

This approach enabled the power station to resume operations safely and efficiently, restoring critical infrastructure and preventing further operational disruptions.

Setting the standard for integrity and excellence in power solutions across diverse industries.
