A parallel processing technique for electrical tree growth in solid insulating materials using cellular automata

Abstract

One of the major problems in an electrical insulation structure is its failure while operating at normal voltage stress which is due to electrical treeing. It is well-known that this electrical tree grows progressively and is damaging locally. To analyze the electrical treeing in the laboratory, not being cost effective, computer simulations are used. We have employed a known cellular automata method with new parallel processing techniques to reduce the computation time considering the available parallel processing systems. The major advantage is that the cellular automata algorithm inherently exhibits parallelism paving the way for ample exploitation. Moreover the parallelisation has helped to understand various aspects of electrical treeing also in a simple way.
