Comparative Measurement of Partial Discharge Using Spiral Antenna with RC Detector on High Voltage Equipment

Abstract

Abstract Partial discharge is a partial electrical discharge event in isolation that is not directly connected between the two conductors, which discharges can occur either near or not on the conductor. An Archimedean spiral antenna is created to detect partial discharges in high voltage equipment. Electromagnetic waves produced by partial discharge will be detected by the antenna which has a frequency range of 300 MHz - 3 GHz. The next measurement of partial discharge uses an RC detector. The purpose of this study was to determine the performance of Archimedean spiral antennas which were then compared to RC detectors. Based on the results of tests carried out as many as 50 times, both the spiral arsenic antenna or the RC detector showed good results. Antennas get slightly lower yields, due to the reduction in the flow of electromagnetic waves on the metal walls of high voltage equipment. Whereas RC detector is better by displaying more sensitive results.
