Application
The device is used to apply AC voltage on capacitive voltage transformer to measure its error at power station site.
Features
Combine reactor with standard voltage transformer as one module, which is a creative structure that is used for the first time
Low noise in running and mechanical strength is strong enough
Compact structure, space-saving
Hydraulic pressure device for lifting, easy to operate
Insulated by SF6 which is good at automatic-restoration, operation is reliable and safe
