Comparison of Partial Discharge Characteristics Detected by RC Detector and Rectangular Antenna

Abstract

Abstract This study discusses the method of measuring and detecting Partial Discharge (PD) in high voltage electrical equipment that has the characteristics of being veiled with metal. This research uses the UHF (Ultra High Frequency) method based on IEC 60270 and RC Detector to detect and measure PD. This method uses electromagnetic wave energy emitted by PD sources from the metal box. Use this method to get detection and measure without having to activate the test object. Then the sensors used in testing in this study are rectangular spiral antennas and RC detectors. In addition, various stresses will be tested. The measurement results then compare when evaluating the PD between the Rectangular Spiral antenna and the RC Detector to determine the sensitivity level of the rectangular spiral antenna. The test results show the measurement of partial release of rectangular spiral antenna is greater than outside the metal box and measurement using RC Detector is more sensitive than using a rectangular spiral antenna sensor.
