DFIG IP Test
DFIG IP Test
(OP)
Good Morning
Last days we was done some DFIG wind generator inspection including Stator and Rotor PI test.
The rotor wires was not disconnected on the slip rings only the brushed raised and insulated and the PI was done ussing a megger.
The question is if we found low rotor IP values (1.1-1.5) could the slip rings be part of this bad reading?
Did the ring play a fundamental roll in the insulation polarization? if yes How
Thanks for the inputs and regards
Carlos
