AbstractWith the deregulation of the power system network, prioritizing capital investments and reducing operational costs while maintaining a reliable supply has become a priority for asset managers in utilities. A shift from a corrective-or time-based to a condition-based maintenance strategy for the utility infrastructure has therefore become an essential task. For example, a significant portion of the underground medium voltage XLPE cables in the electricity grid has been in service for periods longer than their nominal designed life, and therefore an asset management decision has to be taken to replace, refurbish or maintain these cables in service. Such a decision requires a reliable condition assessment method based on accurate diagnostic measurements that can determine the health index of the cable-under-test (CUT).
