Electrodynamic Studies of Bundled Conductor Spacers

Fault currents up to 54,000 peak amperes were imposed on bundled conductors equipped with instrumented and prototype spacers. Special instrumentation techniques were employed to gather experimental data from these spacers. The data were used to verify a mathematical analysis of the dynamic force problem. Comparison of experimental and analytical results shows them to be in good agreement; a mathematical model, therefore, may be used to direct future spacer design, eliminating the necessity of costly outdoor test programs.
