SUMMARY
The discussion centers on a 600V 3-phase generator exhibiting unstable voltage output, specifically voltage clipping and distortion in phases B and C at 690V, while phase A peaks at 840V with crossover distortion. The issues raised include potential causes such as load connection, recent maintenance, and signs of overheating insulation. Participants are encouraged to investigate the generator's operational conditions and maintenance history to diagnose the problem effectively.
