Causes, Hazards, and Treatment of Generator Rotor Grounding
The grounding of the rotor of the generator has one-point grounding and two-point grounding of the rotor. In addition, there will be short circuit faults between rotor layers and turns. Like stator grounding, rotor grounding can be divided into instantaneous grounding, intermittent grounding, permanent grounding, internal grounding and external grounding, metallic grounding, and resistive grounding.
