In order to supply small communities or facilities in sparsely populated, remote rural areas, tapped transmission lines provides an attractive solution to the challenge to provide connections at minimum cost. Using a tapped line saves the costs of building a sub-station at the point of connection together with those associated with the need to break the line. Unfortunately however, introducing a tap in the line greatly complicates the protection. The situation is further complicated by the increasing use of distributed generation which can be connected to the system. This paper introduces a novel protection scheme designed for protecting multi-terminal transmission lines. It also has the ability to be extended if and when new taps are added to the circuit. This scheme is based on a conventional carrier assisted, distance relay protection scheme and is designed to accommodate variations in tap position.
