Application of Digital Signal Processing to Improve the Accuracy of Fault Location Determination in Power Transmission Lines on the Basis of Fault Regime Parameters

Resumo

Remote means for fault location determination are intended for finding the most likely fault point and reducing the bypass zone of the line. Methods of improving the accuracy of the calculation of the distance to the fault location (and reducing the inspection zone of the OHL) owing to the use of special digital processing of fault regime oscillogram signals are examined.
