摘要：
In this paper a new numerical algorithm for arcing faults detection and fault distance calculation is presented. The solution is given in the rime domain and for the most frequent single-phase to ground fault. it was derived by processing the line terminal voltages and currents. The new algorithm can be utilized for blocking the automatic reclosing. A simple square wave are voltage model was assumed to represent the long are in free air: The unknown model parameters (the line resistance and inductance, and arc voltage amplitude) were estimated by using "Least Error Squares Technique". The new algorithm was successfully tested by computer-simulated and laboratory tests.
