Water tree in polymeric cables: a review

Abstract

The power cable breakdown suspected due to water treeing in polymeric cables are said to be the main cause. The inconsistent and unreliable nature brings out the importance of research in water treeing detection in polymeric cables. Early detection of water tree in polymeric cables is important in order to increase the cable efficiency by reducing the timeframe of the cable failure. This paper presents a comprehensive review of water treeing detections in polymeric cables, in particular, the relation to the background of water treeing, the types of water treeing, experimental investigations on water treeing, and factors affecting the initiation and growth of water trees.
