SIMULATION OF CORONA RINGS IN THE CHAIN DIMENSIONS OF COMPOSITE INSULATORS BASED ON CREATING UNIFORM ELECTRIC FIELD INTENSITY

Field intensity distribution in the space around the chain of insulators used in transmission lines that distribute the electric field intensity and voltage gradient in the space around the blades close to the line more than other points That this can destroy the insulation and reduce the insulator chain its useful life is serious. Therefore, one of the strategies that can prevent the effects of this phenomenon is use of corona rings. Articles have been published recently on the impact of corona rings surrounding electric field distribution chain insulators Chinese consider said. But the fact that nowadays the use of composite insulators in transmission lines are developed in this paper the distribution of electric field and voltage gradient around the composite insulators is examined.
