Abstract :
Errors in partial discharge (PD) location on high voltage dielectric cables caused by both mechanical and electrical phenomena are discussed. The sources of error relevant to PD location include errors in measuring time delays, scatter caused by noise and disturbances, pulse propagation distortion, errors in cable length measurement, and trivial errors in experimental technique. Experiments to determine typical PD location error were carried out using a detector with a 10 MHz bandwidth. Extensive tests were carried out on a 200 m, 15 kV cable with metering marks on the outer sheath, as well as a 590 m, 10 kV cable without metering marks.<>
