Analysis of Multiple Electrical Trees Incepted at Wire Electrode Test Object by Means of PD Detection
Paper in proceedings, 2013

This paper introduces a method allowing characterising the growth of electrical trees in wire-plane electrode objects. By applying both electrical and optical measurements the inception level and the number of trees were analysed. It is shown that the results observed optically closely resemble the electrically detected PD behaviour, thus exhibiting a good correlation between both the methods. This indicates a possibility for analysing electrical treeing process in non-transparent materials based on the electrical measurement only and opens for an efficient approach in evaluating new materials for cable insulation.
