Abstract : A new fault location algorithms with consideration of arcing faults calculation based on the two end synchronized data for high voltage transmission line is presented in this paper. In this algorithms we used least error square (LSE) principal without considering line parameters. The least error square principle is used on positive sequence equivalent circuit to calculate the fault distance from the reference bus. This algorithms is simple in calculation for lumped or disquieted transmission lines, as well as require less data and also non-iterative in nature. Due to the requirement of two end data, this algorithms provide promising performance against the variable fault resistance. In addition, as it use only positive sequence circuit only, it suitable for all type of faults i.e. symmetrical as well as unsymmetrical. The PSCAD transient program is used to perform the faults cases and Matlab is used for calculation of fault locator performances as per the algorithms. The results provide evidence of performance of algorithms through investigation using a detailed simulation of a selected 200 km overhead transmission system. Index Terms- Fault location, Line parameters, synchronize or Un-synchronize data, LES (Least Error Square), Lumped parameters, Distributed parameters, Transmission line.
