Diagnostics of HV power cables are playing an important role in the meaning of two aspects: 1) on-site diagnostic of new installation， where a commissioning test has to prove the absence of any defects in the cable insulation and accessories， after transportation and installation。 2) On-site diagnostic of a serviced aged power cable where the condition after a period in service or information about workmanship of repairs has to be known。 As it is known some installation defects can result in breakdown even after a successful after-laying test。 Obtaining more diagnostic parameters like; Withstand Voltage， Partial Discharges (PD) and Dielectric Loss (tan δ)， providing a indication of insulation condition and accessory performance。 In this paper several examples of on-site tests on new and serviced aged XLPE HV power cables will be discussed。 Examples of: after-repair， after-laying， and condition assessment tests will be presented as performed with Damped AC diagnostics。
