N2 - Surface discharges occurring in high voltage equipment such as insulators and bushings can lead to interruption of the power supply. Industry and manufacturers are increasingly using polymer material, especially in outdoor insulation. During service, insulation surface degrades over time due to high field stress, aggravated by hostile environmental factors such as temperature, humidity, and pollution. Thus, the early detection of surface discharge can help prevent such damage that may lead to disruptive faults. The UHF method, which has so far been used for gas-insulated (GIS) systems, is increasingly attracting interest for use as a non-invasive technique for PD detection in outdoor insulation systems. In this paper, a numerical simulation of surface discharge in air-solid insulation interface and the response of a UHF sensor to electromagnetic (EM) waves excited by the discharge using the Finite Element Time Domain (FDTD) method is carried out.
