New Algorithm for Rotor Ground Wall Condition Assessment of Large Salient-Pole Generators
Electrical Insulation ConferenceDeterioration of ground-wall insulation is one of large salient poles generators failure modes. A failure in this insulation can seriously compromise the machine's operation, causing stray current circulation between poles, leading to vibrations, and ...
