Abstract

High voltage insulation failure has been a main cause of high voltage systems for a long time now. It is found that this phenomenon occurs due to the existence of partial discharge in voids found in insulation of cables, especially XLPE (Crosslinked polyethylene) cables. Partial discharge normally exists in voids in cables which are produced accidentally during the extrusion process of cables. However, improvisation of XLPE cables from one generation to another generation has reduced voids gradually and thus, reducing the threat of partial discharge. Yet, the effects of partial discharge could not be underestimated as it would lead to serious breakdown and electrical apparatus failure. Therefore, partial discharge testing by using a partial discharge detector is one of the main tests used to determine the quality of the XLPE cable so that the necessary steps and precautions can be made on the cable if the cable does not meet the requirements of the test. In this project the insulation condition of an XLPE cable with different types of artificial defects will be tested for partial discharge and the results analysed and discussed. The complete procedures for doing the testing are also described in this thesis.
