Abstract :
This paper applies genetic arithmetic to the inverse problem in electric-field of high voltage insulators, finding an optimized solution for the inverse problem in electric-field and establishing an optimization calculation model. After measuring the electric-field of measuring points in the vicinity of insulator strings, calculating the actual voltage distribution along the insulator string by the method of charge simulation and genetic arithmetic, then comparing the actual voltage distribution with the standard distribution of the voltage along the insulator string, according to that can make sure whether there are defective insulators and the approximate position of defective insulators. The optimization calculation can increase precision of non-touch electric field mapping method, and detect defective insulator well and truly.
