Abstract: This study presents a coupled electric–magnetic–thermal–mechanical analysis of various busbar arrangements under short-circuit conditions. The open construction of busbars increases the risk of faults, e. by the ingress of foreign bodies into air gaps, and the risk of consequent damage is high due to their high normal operating. IEC 61439 requires busbar systems in LV assemblies to be verified for short-circuit withstand strength, not just current-carrying capacity. Busbar support spacing is a critical design variable: wider spacing reduces short-circuit withstand rating. Verification under IEC 61439 can be done by testing. Presented at the 28th Saxon Conference on Forming Technology SFU and the 7th International Conference on Accuracy in Forming Technology ICAFT, Chemnitz, Germany, 2–3 November 2022. As a joining-by-forming process, clinching and the use of functional elements enable low-energy joining of components.

This chapter focusses on the design implications of connecting or rigid, single or bundled conductors to HV equipment with connectors/clamps, either bolted, welded or compressed. They may be used in a variety of configurations ranging from vertical risers, carrying current to each floor of a multi-storey building, to bars used entirely.
