| Abstract: | The non-sinusoidal cycle detection signal into sinu- soidal signal within 1/3 of the cycle is divided.In this three pe- riods of time,it builds the equivalent circuit model and math model of system separately.The change connection between leakage current,grounding current and leakage resistance are presented and validated by experiment data. |
