Condition Assessment of Medium-Voltage XLPE-Insulated Cables Degraded by Water Treeing

In Australia, degraded underground XLPE cables are causing disruption of electricity supplies and high community costs.  There is no reliable non-invasive technique for predicition of cable condition to optimise cable replacement and refurbishment.  In this project, a large scale experiment is in progress on 22kv cables to ascertain the effectiveness of a new cable refurbishment technology.  New techniques for assessment of cable condition will be developed using unique data from the ageing experiment and computer models of fundamental phenomena.  Successful conclusions from this project will save the industry partner and other electricity distribution companies tens of millions of dollars.
