Abstract :
Insulators for overhead lines are considered to be of basic importance to the transmission system. This paper describes a new method to check defective ceramic insulators by finding the solution of the inverse problem in the system containing insulators strings. Measure the electric field of given points in the vicinity of high voltage insulators string, calculate the voltage distribution of the insulators by charge simulation method (CSM) and Newton method. Compare it with normal voltage distribution to check whether there are defective insulators in the string and the position of them
