Fault Location in Double Circuit Medium Power Distribution Networks Using an Impedance-Based Method

Abstract: The distribution network is extended throughout cities, towns, and villages. Because of the increase in loads and the decrease in power passageways and public corridor reduction, double circuit lines are increasingly being used instead of single circuit lines. Fault location in double circuit power networks is very important because it decreases the repair time and consequently the power outage time. In this paper, a new improved method for fault location in double circuit medium power distribution lines is pr… Show more

“…Due the specific operation-identification of the segment affected by the fault is compared with similar solutions-fault indicators and distance protection is compared in Table 1. Different fault location methods are compared in [32]. According to preliminary investigation it is possible to detect 2 phase to ground faults using cable screen earthing current.…”
