Investigation of electric field distribution on A C composite insulator using corona ring

In high voltage side insulators play excellence role in transmitting power. The major drawback in high voltage insulator are the field distribution it is not uniform along surface when this field increase it lead to corona discharge. E-field magnitude increase near high voltage side end fitting. This paper deals with the use of corona ring to improve the electric field distribution on live high voltage end fittings of composite insulators. Potential and E-field distribution were analyzed on 230kVIn high voltage side insulators play excellence role in transmitting power.
