Early fault detection tool prevents major generator damage in a European CCGT power plant

Using its early fault detection tool, Laborelec was able to identify a dangerous temperature increase in the generator of one of the units of a European CCGT power plant in the Netherlands near the end of November. After having notified the local operator, the unit was immediately shut down for closer investigation. Various tests revealed that parts of the generator’s stator had been damaged.

Without Laborelec’s SmartSignal detection tool, the plant would never have detected the problem before the temperature reached 150°C. By that point, the damage could have been catastrophic. It could have necessitated a complete replacement of the generator, which is vastly more expensive than replacing the damaged stator parts.
