Abstract

In this paper, the effect of applying a thin mu-varistor material layer to composite insulator structure is presented for the rain test. In the finite-element-method (FEM) simulations, thin resistive layers are modeled as 2D surfaces instead of 3D volume bodies which helps to avoid problems within the geometric modeling process and moreover results in less degrees of freedom. Numerical simulations with this technique are presented for high voltage insulators with nonlinear field grading materials.
