【Abstract】 A new method for tie capacitance current measurement is presented.An adjustable reactor is connected in parallel to the peterson coil,and they are connected in series with the open-delta side of zero sequence voltage transformers.The capacitance current can be calculated by injecting varying frequent current and measure voltage signal in distribution systems.Experimentation results show that the proposed method is with high precision,wide measurement scope and convenience.更多还原
