Condition assessment of high voltage power cables

In this contribution based on experiences made in the Netherlands, for condition assessment of HV power cables systematic approach has been developed. Based on the assumption that there is not one dominant failure process in HV cable networks, PD in the cable insulation cannot be seen as the only messenger for failures: the complexity of cable systems in HV networks is often higher (e.g. oil-filled, gas-pressurized cable systems) therefore different approaches have been investigated and implemented in the last five years.
