Analysis of galloping amplitude for conductors with interphase spacers

Abstract

Ahtrurt -The main purpose of this paper is to calculate the behaviors of interphase spacers to reduce the ampIitude of galloping in conductors. In simulation, three phases and iced-singIe/two-bundles conductors with/without spacers are considered in viewpoint of standard cases. The implicitlexplicit finite element methods are used to calculate the transient response with geometric nonlinear behavior. ANSYS/LS-DYNA program is also applied. Calculation results can be used to predict the positions to insert the interphase spacers between conductors.
