Analysis of electrical safety level test for barehand work at 765kV vertical double circuit six bundle conductors T/L in Korea

Nowadays hot-line work is a general maintenance method in most countries. Specially, 765 kV vertical double circuit six bundle conductors transmission line constructed and operating in Korea, necessity of the live line work is grow up, due to the difficulties of the power suspension, most towers on the mountain, big sized towers and high costs of the generation constraints. The 765 kV transmission line will be maintained by live-line work for efficient operation. In order to maintain the 765 kV transmission lines safely by barehand work, preferentially, we should know the analysis of electrical safety level test. This paper studied about analysis of electrical safety level test in live line work at 765 kV vertical double circuit six bundle conductors transmission line.
