On-Line Monitoring Analysis of Aeolian Vibration of Jiangmen-Tongtangjia 220kV Transmission Line

Abstract

The Aeolian vibration of coastal overhead transmission is a well-known phenomenon which leads to fatigue damages of conducts. This paper introduces the information and the arrangement of on-line monitoring equipment for Jiangmen-Tongtangjia 220kV transmission line, analyzes the data acquired by on-line monitor and advises the improvement of the selection or install location of stock-bridge damper of conducting wire, which prevents the breakage of conducting wire due to Aeolian vibration. 
