Abstract
Arcing faults (AFs) have probabilistic and nonlinear nature which is related to environmental parameters. Thus, the conventional fault location methods can not locate the AFs, accurately. This article puts forward a novel and precise AF location technique for multi-segment combined transmission lines which uses unsynchronized measurements from two terminals of the line. The method consists of stages; the number of them is equal to the number of segments plus one. This scheme does not need to employ a selector to identify the faulty segment of the line. Finally, the case studies are carried out using MATLAB/Simulink with variations of fault conditions including fault distance, type, incidence angle and faulty segment of the line, and also with variations of synchronization angle which show that the presented method provides a high accuracy in AF location under various situations.
