First field experience of on-line partial discharge monitoring of MV cable systems with location

A new measuring system is presented for the on-line monitoring and location of partial discharges (PDs) in medium-voltage power cables. The system uses two inductive sensors, each at one cable end. The measuring system is called PD-OL, which stands for PD detection Online with Location. A pulse injection system is used for the time synchronization of the data intake at both cable ends and for the on-line calibration. PD data is send via internet to the KEMA Control Center for interpretation and final presentation, made visible on a secured web-site for the network owners. This paper discusses the basics of PD-OL and a number of measurement results.
