Abstract :
This paper suggests that a voltage recorder, placed next to a circuit breaker not as usual on the side of the substation, but on the side of the transmission line, may reveal the location of permanent faults. Two different approaches on estimating the fault location are presented here: a frequency domain approach and a time domain approach. These methods are tested and compared with simulations of typical transmission systems using the Electromagnetic Transients Program (EMTP). Two typical line configurations are considered: two terminal lines and three terminal lines.
