Review of Transient Earth Voltage Sensor Implementation to Detect Partial Discharge in High Voltage Equipment

This paper reviews the implementation of a Transient Earth Voltage (TEV) sensor to detect partial discharge in high-voltage equipment. The use of TEV as a partial discharge sensor is one of the main choices recently because of its ease of use. Research regarding the implementation of TEV has been carried out by many researchers. The research conducted is mainly for metal-enclosed high-voltage equipment such as GIS, Transformers, etc. The main purpose of this paper is to provide a reference related to the development of TEV implementation research for high-voltage equipment. From the review conducted, it can be known that there are some common methods for comparing TEV sensor performance with other sensors based on the comparison of PD measurement which is implemented in 6 types of high-voltage equipment. By comparing parameters such as frequency value, occurrence time, duration, PD pattern, waveform shape, etc., a more in-depth analysis of the characteristics of partial discharge detected by TEV or its comparative sensor for each equipment or type of defect can be determined.
