Partial Discharge Analysis on Crossed-linked Polyethylene (XLPE) Cable 150 KV

Abstract

Partial discharge is the flashover of sparks that occur in an insulating part. as a result of the high potential difference in the insulation. Partial discharge can occur in solid insulation materials. It is play an important role in the electrical power system to separate two or more conductor of electric voltage. So, between these conductors do not occur flashover. The material was chose as the insulation material for high voltage equipment is polymer material, it is because in addition to having a high breakdown voltage. Polyethylene is one of the materials included in the polymer group, generally better known as plastic because the material is thermoplastic. There are several methodologies before conduct this research, that includes literature studies. Literature Studies is a research method by finding material from various libraries on topics that will be discussed in this research. Do Partial Discharge testing. And then, record the data obtained. From the experiments that have been done, the results show that a good Partial Discharge value is below 10 pC, if the cable has more than doubled from the normal value, the cable have been damaged or have been consumed by the age of the cable.
