Analysis of galloping amplitude for conductors with interphase spacers

The main purpose of this paper is to calculate the behaviors of interphase spacers to reduce the amplitude of galloping in conductors. In simulation, three phases and iced-single/two-bundles conductors with/without spacers are considered in viewpoint of standard cases. The implicit/explicit 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.
