A study of water tree frequency dependence and growth rate in polymer

Abstract

This paper presents theoretical and experimental studies on the water tree (W.T.) growth rate frequency dependence. The high growth rate experienced is explained on the light of the simulating circuit components and parameters. The results are very sensitive to the assumed water content in tree and the original tree length. Attempts were made to correlate between W.T. theories and experimental results. The mechanisms of W.T. initiation and growth are explained.
