In recent years

galloping has emerged as a significant threat to the safety of overhead transmission lines.However

there is a dearth of effective evaluation methods for line galloping risk as well as anti-galloping devices

particularly those that are quantitative and comprehensive.This paper

grounded in a thorough examination of triggering mechanisms

line structures

and meteorological factors

identifies two critical elements to focus on:ice thickness and wind speed. Utilizing statistical weighting

a numerical quantification method for galloping risk is introduced. This method comprehensively assesses the interrelationships among design conditions

such as galloping zones

wind zones

and icy zones

and the risk of line galloping both before and after the installation of anti-galloping devices.The evaluation results are presented in percentage form.Using a500 kV transmission line project as an example

the study analyzed the necessity of anti-galloping measures and the differences before and after the installation of anti-galloping devices

quantitatively demonstrating the rationality of these measures.The findings of this study offer a reference for optimizing the application of anti-galloping devices in anti-galloping design work of line design

operation

maintenance

or technical upgrades.
