Dynamic loads on transmission line structures due to galloping conductors

During ice storms, transmission line systems can be extensively damaged due to galloping conductors. The design of support structures and components requires a means to determine the dynamic forces during galloping. This paper presents a procedure for determining the forces on insulators and crossarms due to the large amplitude vibration of ice-loaded conductors. Wind tunnel experiments were conducted to verify the design procedure and to increase understanding of the galloping phenomenon.<
