A Stability Estimation Method of Subspan Oscillation on Overhead Transmission Lines

가공송전선로의 서브스판 진동에 대한 안정성 평가기법

This paper presents a stability estimation method for subspan oscillation on overhead transmission line. It has been used method by conductor's fatigue limit or subspan oscillation amplitude. But it is not proper to estimation of subspan oscillation. We suggest to instability index for estimation method of subspan oscillation. And we tried to 4 bundled conductor system. This result will use to establish of the subspan location rules.
