Analysis of Cable Sway Mode by Combination of Galloping Video in Checking Power Line Facilities and Cable Sway Simulation

Abstract

Sway of transmission lines under typhoon and heavy snow sometimes causes short and break of tower. Short and break of tower make black-out. When they estimate the reason, they investigate the sway mode of cables. This paper presents the analysis of sway mode by combination of Combination of galloping, which is one of phenomenons of sway cables, video in checking power line facilities and cable sway simulation. Using real galloping video, one example of analysis of estimation of cable sway mode is also presented.
