Pilot Wire differential protection system is installed in the Power networks. In this system a pair of metallic cables is used for connecting the two relays located at both ends of a distribution line. This work studied ways to improve the reliability and stability of the pilot wire protection system by using duplication and diversification of the pilot wires. This work presents the calculations relating to design of duplication and diversification of existing pilot wire protection system in the Darwin area without using any new investment. It is found that duplication is possible in the...
