Conventional fault location systems which use one-terminal ac voltages and currents are difficult to apply to multi-terminal systems. This paper discusses new fault location systems for multi-terminal two parallel transmission lines and single transmission lines. The feature of fault location methods in the paper is to convert the original multi-terminal system by progressively conversion to a system with one fewer terminals to arrive at a 3-terminal or a 2-terminal system containing the fault, then to apply the fault locating operation to this 2 or 3-terminal system. Asynchronous sampling at each terminal is preferred in order to simplify the communication equipment and the methods using asynchronous sampling data is presented.
