AC Hipot & voltage Calibration set

AC Hipot & voltage Calibration set

  • Application

    The device is used to apply AC voltage on capacitive voltage transformer to measure its error at power station site.


    • 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
