Investigation of High Power Bolted Busbar Connectors with Longitudinal Slots

In this paper high power bolted busbar connectors which pads and busbars are sectioned by cutting one or two longitudinal slots in order to increase the real contact area and to improve the reliability of their performance are investigated. Applying the method of finite elements models of contact pressure, contact penetration, electric current density and Joule heat are obtained. It has been estimated that the new cases lead to a raise in contact pressure P and contact penetration ? in the interface between the busbar and the pad.
