Abstract

In this article, a computational model is presented which can be used to predict the heating of insulating material surfaces by low-current high-voltage arcs. The discharge is represented by a so-called three-cylinder model. Based on this, the heat flows onto the insulating material surface and its heating by means of thermal conduction and convection are calculated. The calculation results are compared to the measurements of the surface temperature on a model arrangement. The overall model reproduces the dynamic behavior of the heating very well. The quantitative deviations from the measurement are only in the range of a few percent.
