Dspark Duration? 6-15 cycles, a few times longer, no explanation. Most of the time just one phase.
The motor is a 100 hp. connected to a deep well pump. There has been two motor rewind shops involved that I know of. I Know that
if there is core damage to the motor that is not corrected it can create a hot spot in the windings near the core damage that could
result in premature failures. Do you think this is a possibility?
