Polarization testing of MV drives
Polarization testing of MV drives
(OP)
Gents,
I have a 3 phase 60hz 11kV syncronous induction motor, 15 years old in the North Sea.
Insulation class B
Hazardous rated Exd
I intend to do a PI test PI= R10/R1, have you any information on what DC voltage I should use for this test.
The rule of thumb appears to be 2.5kV and I note IEEE 43-2000 refers to 1kV DC for machines post 1974.
Any help/advice appreciated on what the voltage should be?
