Abstract

PT of epoxy mold type have tendency to occur dielectric breakdown in high voltage system. These are using for measurement of voltage or protection of system and application voltage is 25.8kV. Therefore, for improving a lots of problems like as partial discharge, we had analyze on the destroyed Epoxy molded type PT and processing of production. As a results, we concluded that the reason of dielectric breakdown was defect of processing and degradation of insulation by electrical stress. In this work, We presented a method of solution in processing of production. which is reduction of the PO which was occurred at the insulation material. so we must many try to remove faults, these problems are mainly to winding methods of 1st coil. the other side, Reformation of 1st coil improved property of PD and we could prove it with experiments.
