FKWJF induced withstand voltage and partial discharge equipments are used for on-site induced withstand voltage and partial discharge testing of power transformers and PTs of 110KV~500KV. The variable frequency power supply equipped in this test set ensures itself free from partial discharge.The whole test set enables the following tests of transformers by enhancing test frequency(100Hz~200Hz).

 

• Main configuration

?PD free variable frequency power supply
?PD free excitation transformer
?PD free compensating reactor
?PD free HV test reactor
?PD free capacitive voltage divider
?Partial discharge detector
