摘要：

In this paper, in the neglect of the core of the magnetic hysteresis, eddy current effect and the core skin effect and based on the analysis and summary of previous experience, an analytical method to determine the parameters of the transformer's turn to turn short circuit fault is improved and perfected in order to determine the parameters of the transformer when the turn-to-turn fault and turn-to-ground fault happens at any position of the transformer. Through the mathematical model of transformer after fault, we can obtain the node voltage equation of the simulation network. And then we adopt three principles to calculate the unknown parameters in the node voltage equation we obtained before. Simulation results verify the effectiveness of the proposed algorithm.
