Abstract

High voltage (HV) equipment condition monitoring has become compulsoryin the power utility supplier activity since the discovery of multiple failures on HV equipment during operation. The total cost of replacement and installation of HV equipment will cost millions of dollar sand the loss of revenue of no supply period during the breakdown. Insulation parts in the HV equipment are the most important component that closely related to the reliability of the electrical system. The insulation part can be solid, liquid, or gaseous form eventually degraded due to existing stresses (electrical, chemical,and mechanical) in the equipment. One common phenomenon called Partial Discharge (PD) associated with HV equipment insulation degradation highlighted in this manuscript, and these situations intensively researchedover the century. In this review paper, there are few conventional detections, recent detections, recognition techniques, and location techniques are discussed to explore the available methods to analyze further on the area for the future researcher. The objective of this review to present the latest PD associated techniques and facilitate and convey new information for a future research project.
