THEORETICAL STUDY ON FAULT LOCATING METHOD IN AT FEEDING CIRCUIT

The reactance type fault locating method has been used for electrified railroads with autotransformer feeding system. Although this method has given actual results, the error is too large, about 8 kM at maximum, and increases when the fault line is unknown. The autotransformer neutral current type fault locating method, although not yet proven in service, promises to be a better method since the ratio relates with the distance linearly, does not relate with fault resistance, yields high accuracy of fault location, and the distance ratio straight line is easy to draw. Calculations of the fault currents and ratios are presented.
