Abstract

PURPOSE:To discriminate an accident beyond the opposed terminals of parallel two-wire circuit transmission lines with good accuracy, by respectively locating a trouble point from the quantity of electricity and set quantity from the transmission lines by the first and second operation means when a system accident is generated and using these results to judge whether the trouble point is between opposed terminals or in the vicinity thereof by a judge means. CONSTITUTION:An operation means 1 uses the voltage value of the own terminals of parallel two-wire circuit transmission lines and each circuit zero phase current value to locate a trouble point x1 according to a predetermined formula. An operation means 2 uses the own terminal voltage value, the current value and transmission line impedance to locate a trouble point x2 according to a predetermined formula. Then, by a judge means 3, the locating result x1 of the operation means 1 receiving no effect of branch load or trouble point resistance is outputted in the case of the accident between the opposed terminals and in the vicinity thereof and the locating result x2 of the operation means 2 is outputted in the case of an accident beyond the opposed terminals. By this method, an accident point can be located with good accuracy.
