An Analysis and Comparison of Partial Discharge Signal Detection and Localization using SDR and radiometric sensor

Abstract

Partial Discharge (PD) is an electrical discharge that occurs within part of the dielectric between two High Voltage (HV) conductors. PD causes damage to the dielectric which typically deteriorates with time. If left untreated, PD may result in catastrophic insulation failure, HV equipment destruction, and power supply disruption. PD detection plays a vital role in electrical power stations, it can help protect HV equipment. In this paper a comparison between two PD detection systems is presented. These systems are: PD detection system based on SDR technology, and PD detection system based on Radiometric sensors. Both systems can be deployed in a network to perform as a wireless sensor network. Results obtained using SDR technology are then compared to results obtained with the radiometric sensor.
