摘要
An arrangement that includes a transmitter unit and a receiver for locating a circuit interrupter associated with a selected branch circuit of a power distribution system. The transmitter is electrically interconnected with the selected branch circuit and produces a sequence of tracing signals in a branch circuit that is to be traced. Each tracing signal is transmitted and detected at times measured with respect to a detected known phase of the signal on the branch circuit. In one embodiment, tracing signals are transmitted on a branch circuit of a 3 phase power distribution system when the branch circuit to be tested has a positive phase and the other phases are negative.
