PI testing on 13.8 kv motors
(OP)
Is there any value in doing a 5000 volt PI test on a 13.8 kv motor. Even if the readings are trended?

5kvdc test of 13.2kv machine is consistent with these guidelines. We use 10kv test at our plant. I don't think using 5kv would be a big problem (there may be slight tip-up if contamination is present). Most important thing for trending is to use the same voltage each time.
