With increased interconnection of distributed generators (DGs) to the feeder, this assumption is violated. Furthermore, impedance-based fault location algorithms assume a radial distribution feeder. Unfortunately, voltage phasors are not always available due to operational constraints or equipment failure. Moreover, impedance-based fault location algorithms require voltage and current phasors, captured by intelligent electronic devices (IEDs), to estimate the fault location. Identifying the best fault location approach, therefore, requires a thorough understanding of the working principle behind each algorithm. Each algorithm has specific input data requirements and make certain assumptions that may or may not hold true in a particular scenario. In an effort to provide system operators with an accurate location estimate and reduce service restoration times, several impedance-based fault location algorithms have been developed for transmission and distribution networks. Short-circuit faults are inevitable on transmission and distribution networks.
