Abstract: A distribution line is de-energized for repairing or maintenance purpose. Fault detection is required in order to reenergize the line safely. It is more difficult to detect the fault in de-energized lines as it requires system level voltage production and execution to downstream. Implementation of asymmetrical fault detection technique by controlling a thyristor-based device is proposed in this paper. The proposed method involves injecting a thyristor-based controllable signal to the de-energized feeder. The responses of feeder voltage and current are observed to identify if a fault still exists. A thyristor gating control strategy and fault detection algorithm are also developed to detect all types of asymmetrical faults that can occur in the system. The effectiveness of the proposed method has been verified through MATLAB simulation
