SpletAbstract: THE mechanical forces acting on busbar supports during short circuit are determined both by the magnitudes of the mutual electromagnetic forces exerted among the bus conductors and by the elastic properties of the supporting structure: its motional resistance, natural frequencies, and physical nature and arrangement. Comprehensive … Splet02. nov. 2010 · Re: short circuit force calculation. The force primarily depends on the short circuit current flowing through the busbar. The busbar shall withstand the force applied by the fault current. The rating for the capability of the busbar to withstand this force is called bracing, it is generally expressed in kA of r.m.s symmetrical fault current.
