De-energized tap-changers are used to adjust the voltage setting of oil transformers. Unlike on-load tap-changers, the adjustment of the desired winding tap must take place with the transformer turned off.
This type of tap-changer is comprised by tap-changer body and operating mechanism. it is suitable for oi-immersed poweltransformer wth freguency of 50, 60Hz, highest voltage for equipment 40.5kV and 126kv, rated current from 200 to1 500AThe tap-changer is installed on tanking body and operating on tank cover, they must be working under non-energizedcondition.
