Abstract

This paper presents breakdown test of Polyvinyl chloride hard (PVC), Polymethyl methacrylate (PMMA) under non-uniform electric field in transformer oil. PVC and PMMA are placed between point-plate electrodes. The result of the experiment shows that the breakdown voltage of point-plate electrodes is lower than point-point electrodes. PVC endures more breakdown voltage than PMMA. The breakdown voltage of transformer oil with double barriers placed close to electrode is maximum value at 216.5 kV and it is higher than that for single barrier of 205 kV. The results of the experiment can be used to design the blockage room between the conductor and ground in the transformer oil which has the limit space and can endure high breakdown voltage, and it suits the non-uniform electric field characteristics as well.
