Diagnosis test of power cables using a resonant test system and analysis of partial discharge on site

To after-laying of new-installed high voltage (HV) power cables the use of on-site non-destructive on-site testing and diagnosis of new installations of the power cables is becoming an important issue to determine the actual condition of the cable systems and to determine the future performances. An overview is presented on on-site testing using a resonant test system and partial discharge diagnosis of HV power cables with regard to on-site testing methods: AC voltage test of the insulation, diagnostic aspects using partial discharge measurement, patterns recognition using self organizing map (SOM).
