According to IEEE Guide for Reducing Bird-Related Outages, several types of transmission line faults could be induced by birds. The number birds increases as human awareness environmental protection increases. Thus, the probability suspension insulator string flashover bird streamer would also increase. Analysis in Yunnan, China, shows that many occurred winter migration zone, and most towers affected are 110 kV towers. Hence, investigating process strings designing a well bird-preventing...
