Abstract :
A new approach to calculate end leakage inductance of new type damp copperplate is analyzed in this paper. Based on the basic inductance calculation formulas between two long direct wires, the leakage inductance of end copperplate is obtained by taking the end copperplate as a group of long direct wire. Using the calculated parameter, the simulation of a sudden short-circuit test of the machine was carried out. The simulation and test results agree quite well, showing that the formulas presented are correct.
