Single Phase Earth Fault Location in the Medium Voltage Distribution NetworksThis paper gives a description of the single phase earth fault location methods in the medium voltage networks. The single phase earth fault location in the medium voltage distribution networks is problematic now. The technical devices which are using in Latvia now do not allow to detect the single phase earth faults fast and high accuracy. Fast earth fault location should be possible by using the equipments which are calculating distance to earth faults. But precisely calculate the distance to the single phase earth faults in the medium voltage networks is very difficult. The paper presents the single earth fault location methods including the calculation methods for fault distance.

This paper focused on studying an algorithm of earth fault location in the medium voltage distribution network. In power system network, most of the earth fault occurs is a single line to ground fault. A medium voltage distribution network with resistance earthing at the main substation and an earth fault attached along the distribution network is modeled in ATP Draw. The generated earth fault is simulated, and the voltage and current signal produced is recorded. The earth fault location algorithm is simulated and tested in MATLAB. The accuracy of the earth fault location algorithm is tested at several locations and fault resistances. A possible correction technique is explained to minimize the error. The results show an improvement fault location distance estimation with minimum error.
