In this paper a new numerical algorithm for arcing faults detection and fault distance calculation is presented. The solution is given in the time 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 arc voltage model was assumed to represent the long arc 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.
