This paper presented the model of distribution parameters common mode equivalent circuit aiming at the calculation of the bearing current. The distribution impedance characteristic of the winding was considered in this model. Additionally, the analytic method and finite element method was applied to calculate the key parasitic parameters and on this basis the impedance separation method was presented. This method takes the variation of the insulation material into account for calculation accuracy. Based on the impedance separation method the frequency domain characteristic of the key parasitic parameters was obtained. According to the distribution parameters equivalent common mode circuit and the key parasitic parameters, this paper built the simulation model to predict the bearing currents The experiment method of measuring the bearing current was improved, and the experimental platform was built. The calculation result of the bearing current was conforming to the measurement value, which proved the rationality of the distribution parameters model and the impedance separation method. ©, 2014, Diangong Jishu Xuebao/Transactions of China Electrotechnical Society.
