Field Reduction Electrodes for the Possible Improvement in the Pollution Flashover Performance of Porcelain Insulators
In this paper an attempt is made to study accurately, the field distribution for various types of porcelain/ceramic insulators used for high voltage transmission. The surface charge simulation method is employed for the field computation. Novel field reduction electrodes are developed to reduce the maximum field around the pin region. In order to experimentally scrutinize the performance of discs with field reduction electrodes, special artificial pollution test facility was built and utilized. The experimental results show better improvement in the pollution flashover performance of string insulators.
