Nowadays it is thought that distribution power networks have the ability to isolate damaged power network place by making optimal links, to identify the fault character, to recognize the character of transients, to establish the fault cause and estimate the state of electrical equipment. For such an objective, fast identification of the earth fault and its place location is a very important problem which requires reliable solutions. The paper describes the new algorithm of earth fault detection and location which is based on the analysis of the initial processes of the fault and its keystone elements. The earth fault detection and location algorithm has been implemented in distribution network state identification terminals.

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.
