This paper presents mathematical morphology based fault detector for the protection of double circuit transmission line. Three phase fault current of both circuits measured at relay location is processed using mathematical morphology. Performance of the proposed fault detector is tested for different types of shunt faults. The simulation results demonstrate that the proposed mathematical morphology based fault detector accurately detects the fault and identifies the faulty phase of a double circuit transmission line and is not affected by variation in fault parameters
