Study on a new method for overvoltage measurement using CVT

This paper introduces a new method for overvoltage measurements in 500kV power system using capacitor voltage transformer (CVT). It is realized with a voltage sensor installed within CVT as the low-voltage capacitor C3 connection in series with the high-voltage (HV) capacitor C1 and the median-voltage capacitor C2. Simulations studies and laboratory tests in manufactory (NISSIN ELECTRIC WUXI Co., Ltd.) have confirmed the validity and practicability of the technique.
