To decrease transmission lines trip rate, combining with the trip rate and operation faults of high voltage transmission lines of cer-tain area in recent three years, this paper analyzed the causes for the trip and faults and proposed the effective measures to ensure the transmis-sion lines operate safely. The main fault factors affecting the safe operation of the transmission lines are lightning stroke, windage yaw discharge and external force destruction etc. According to the concrete transmission lines operational rule, this paper puts forward the effective prevention and cure measures to raise the safe reliability of transmission lines.
