Abstract: A system and method for detecting location of fault in a cable receives disturbance data from first and second protection relays when one of the first protection relay and/or the second protection relay detects a fault in a section of the cable. The system extracts voltage and current data for each segment in the section using the disturbance data, cable parameters and length of each segment, and determines a fitness value for each segment in the section using the extracted voltage and current data. The system identifies a segment with a lowest fitness value from the fitness value determined for each segment in the section by comparing the fitness value of each segment with the fitness value of subsequent segments in the section and detects the segment with the lowest fitness value as fault location in the cable.
