Finite element solution method on power loss of plateau type and epoxy resin casting current transformer

Along with our country electric power enterprise´s vigorous development, the domestic electrical market tends to the standardization gradually. At the same time, high-parameters, high-performance, high-reliability current transformer who has an important role in power transmission device shortly supplies in the market. This article takes 40.5Kv plateau type and epoxy resin casting current transformer for an example, by finite element analysis method, using ANSYS to have an electromagnetic field analysis and no-load loss solution,the results consistent with the theory, verifies that the solution method is correct and practical, improves the enterprises´ production efficiency and economic benefits.
