Master of EngineeringThis thesis describes the design of an instrument for the protection of personnel carrying out live line bare hand maintenance of power transmission circuits. This instrument monitors the leakage current along equipment to ground and sounds an alarm when preset thresholds are exceeded. The leakage current monitor is microprocessor controlled, resulting in both flexible and user friendly operation. The prototype constructed, has been tested and found to perform very well.
