In this paper, we proposed a Beyond Visual Line Of Sight(BVLOS) drone system for inspection of transmission lines. As drone technology advances, drones are replacing dangerous tasks in the electric power industry. According to this trend, Korea Electric Power Corporation has developed the automatic inspection drone system for transmission lines. This system targeted inspection of transmission lines in the visible area. Since the transmission line is mainly located in mountainous area, the drone frequently enter the invisible area. In order to inspect multiple transmission lines with the existing system, frequent movement for drone takeoff and a lot of preparation time are required. To overcome this problem, we upgraded the existing system to inspect BVLOS transmission lines. For BVLOS flight, laws and regulations must be observed. Therefore, essential functions were derived from laws and regulations, and these functions were developed to be suitable for inspection of transmission lines. Finally, our system was verified through special flight approval from the Ministry of Land, Infrastructure and Transport. Through the new transmission line inspection drone system, the multiple transmission lines can be efficiently inspected at once.
