This techniqueemploys pre- and post-fault current and voltage information along with data from laterals. Inthis method a knowledge based algorithm is incorporated to the superimposed componentsbased fault location and monitoring algorithm to locate shunt faults in radial power distributionlines with sub-feeders. By transferring current information from sub-feeders to the substation,through Shielded Twisted Pair (STP) cables the possibility of multiple fault point locations areeliminated. The effectiveness of this method is tested with Electro-magnetic Transients Program(EMTP) simulations.Key Words: Fault Location, Programmable Logic Controllers, Power Distribution Feeders,Superimposed Components,
