 Fault location on overhead transmission line using phasor measurement unit" is a study for obtaining the accurate location of fault occurred in power transmission. The fault location studies have attracted interest among researchers since 2000 due to the increase in awareness of the importance of providing a reliable and effective utilities services. This study chooses impedance-based, travelling wave and phasor as fault location methods since they are well developed and recognized for providing accurate and reliable results. The power system network is modeled using ATP-EMTP and Power World software, and the outputs are manipulated into calculation based on algorithm. According to the results, the most accurate method is travelling wave, followed by phasor and impedance-based method. This study also discusses factors that affect the results to each of the methods. The advantages of these methods to the power industry include providing improvement in the aspects of reducing down-time, minimising damage, saving utilities cost, etc.
