Abstract :
This contribution presents new developments in the field of on-site (E)HV cable testing, in particular testing of long lengths of power cable. A modern solution is presented for on-site testing and diagnosis of transmission power cables by means of sinusoidal damped AC voltages. With this testing technique on-site voltage testing is performed with additional non-destructive measuring techniques e.g. partial discharges or dissipation factor measurements. To improve the PD detection and particularly the PD location possibilities on long cable lengths an additional range extension measurement system has been developed for PD detection on longer cable lengths. This distributed measurement system can be installed at cable accessories to detect PD signals.
