Field Observation and Analysis of Subspan Oscillatron in 4 Bundled Conductor Transmission Lines

가공송전선로의 서브스판 진동에 대한 실험 및 실측 분석

This paper presents a collection of a number of observations made on 4 bundled conductor transmission lines concerning the behaviour of conductors under the effect of natural winds. Namely in order to know the wind-induced vibration status and study wind-induced vibrations have been recorded and analyzed form the real transmission lines. By the field observation and analysis results, subspan oscillations among the wind-induced vibrations is known to be the main type of the vibrations. And some common characteristics of the observation sites, which have had high maintenance rate, can be found from the data also. It is considered that the main results described in this paper will be useful data and be used in controlling the subspan oscillations and protecting the conductors.
