An Analytical Method to Calculate the Eddy Current Losses of Transformer Shielding Coil

摘要

This paper mainly researches the eddy current losses of transformer shielding coil by adopting for analytical method. This method calculates the conductor's boundary conditions directly by using the analytical solution of the leakage magnetic field, which is generated into the conductor eddy current equation for the analytical formula, then compared the analytical method with the finite element method to fix the analytical formula, the relevant theories are applied to analyze the results of using two different shielding to reduce the losses and find the effectively measures.
