Abstract: To ensure a safe re-energizing of an overhead distribution feeder after it is de-energized for an extended period, a fault detection technique by controlling a thyristor-based device is proposed in this paper. A controllable signal is a feed into deenergized distribution feeder using a thyristor-based device to generate the electrical response. The proposed method involves injecting a thyristor-generated controllable signal into the de¬ energized feeder. By using this technique we also check the false response due to capacitance present in the line. For that purpose, we constructed a simulation diagram in MATLAB. In this paper, we detecting the fault by observing the waveforms of current and voltages. From this current and voltage waveforms, we identify the type of fault on this distribution line.
