Temporary Partial Discharge Monitoring of Power Cables

Partial discharge (PD) is a common sign of insulation breakdown in power cables and cable accessories, such as joints and terminations, which can eventually result in cost-intensive repairs and prolonged outages.

With suitable sensors, PD activity can be monitored and trended on a temporary continuous basis during the operating life of the equipment for troubleshooting in the field. The terminations and joints of the cable system are typical PD measurement points. Powerful noise suppression and PD source separation algorithms are used to reliably localize harmful PD phenomena in the cable system.
