Insulation Diagnosis of High Voltage Power Cables

In this contribution based on field application of advanced diagnostics a systematic approach for condition assessment of HV power cables is discussed. Based on the assumption that there is not one dominant failure process in HV cable networks in addition to partial discharges dielectric diagnosis has also be included to determine the actual condition of service aged e.g. XLPE, oil-filled, gas-pressurized cable insulation systems.
