    Abstract

    In this paper a new numerical algorithm for arcing faults detection and fault distance estimation is presented. The solution is given in time domain. It is based on the line terminal voltages and currents processing. A simple new mathematical model of arc voltage is introduced in the estimation. Thereby, the more accurate approach to fault location is derived, particularly for the close-in faults. The new algorithm can be utilized for blocking the automatic reclosing. The unknown model parameters, including the line resistance and inductance, fault resistance and arc voltage amplitude, are estimated by using Least Error Squares Method. The new algorithm is successfully tested through computer simulation and laboratory tests. © 1997 IEEE.
