On-line Fault Detection to Prevent Network Failure

Application of on-line fault and partial-discharge activity location helps to improve the reliability of medium-voltage underground cable networks.

Medium-voltage underground cable systems are subject to outages, but distribution network operators can improve system reliability in terms of restoration time if the location of faults on the network are located precisely and immediately when they occur. Preferably, improved system reliability could be realized if a fault is predicted before an outage and thereby avoided.
