Guys, thanks for input. (Redsy). I performed two tests the load side of the VFD to the line side of the disconnect.(first test) Then I megged the load side of disconnect (switch open of course) to the motor - no leads disconnected. I talked to another BSE guy today and he told me they have a contract w/ a guy that wound motors for them a while back and he remembers the contractor bringing out an osciloscope(sp) looking thing to test the motor. He said he tested how efficient the motor was running and could determine if the motor was on it's way out... Does anyone know what test he did? Our BSE (bldg. stationary engineer)doesn't remember what type of meter/device he used. I'd like to know. Thanks guys. (Mike Sac Sate Univ)
