Detecting generator rotor shorted turns

Flux probe monitoring and vibration monitoring offer double defensive belt

Changes in a machine’s vibration behaviour can indicate various problems. Vibration monitoring helps detect and diagnose these problems at an early stage. Rotor flux monitoring is a specific tool for detecting shorted turns in generator field windings. Based on these complementary monitoring systems, Laborelec managed to quickly address potential generator rotor issues in two Belgian power plants. The presence of shorted turns in generator field windings is an electrical problem. It has a direct impact on the generator’s integrity and can have indirect mechanical consequences, such as vibrations. Hence, it is essential to detect and address shorted turns as quickly as possible in order to prevent further damage and a potential outage.
