Series resonant frequency step-up device

For CT / VT / CVT (CT / PT / CVT) and other high-voltage electrical equipment partial discharge test and the AC voltage test, to meet the 500kV the CT / VT (PT) / CVT calibration of transformer, no local discharge test and the AC voltage withstand test. Single test sample relative to capacity 500~8800pF, the maximum test voltage of not more than 800kV.
