Abstract

Performing on-site non-destructive testing and diagnosis of HV power cables is becoming an important issue to determine the actual condition of the cable systems and to determine the future performances. Therefore in this contribution based on field application of on-site testing and available advanced diagnostics overview of experiences will be discussed with regard to on-site testing methods: energizing, diagnostic possibilities and to non-conventional PD diagnosis of new and service aged power cables.
