Calculation of distance to fault and transition resistance on the fault place on electric power system lines

Determination of exact distance to faulted place on electric power lines is of extreme importance for shortening of no voltage states in electric power system, minimizing losses and making easier finding of faulted place and transportation of servicemen to it. Many methods have been developed according to existing technologies with the only one aim: to make calculation of distance to fault more accurate. Here presented method is offering fast calculation of distance to fault eliminating influence of transition resistance on the place of the fault and eliminating influence of DC and harmonic components existing in electrical signals during transient process caused by the fault.
