Abstract: A new method is presented based on nullor substitution, which is suitablefor detecting single faulty branch with short-circuit or open-circuit on tree type power network. The required current and voltage values of each port are easy to be measured, and the proposed method needs less computations after measurement. It is feasible for single faulty-branch location on tree type powed network with several branches. Simulation by computer shows satisfactory results. -
