Low-voltage busbar short-circuit analysis

Home / Low-voltage busbar short-circuit analysis

The study presents a comprehensive analysis of bus-bar systems under short-circuit conditions, integrating elec-tric, magnetic, thermal, and mechanical factors. Utilizing the finite-element method (FEM), the authors model the interactions among these phenomena. Abstract: The short-circuit withstanding performance of busbar system is one of the most important safety indexes for low-voltage (LV) switchgear. The formation of electrodynamic forces in the current circuits of electrical energy distribution systems is related to the flow of high currents, but mostly it is related to short-circuit currents. In order to highlight these phenomena, the detailed specification of the parameters during tests is.
