ABSTRACT
Electrical connection in power system is defined as one which exhibits minimum resistance, both at initial assembly and during the long service life. Plated busbars outperform unplated busbars by providing stable contact resistance (CR) and a low maximum operating temperature that increases the service life of the bus joint. In electrical industry, sections of the bus structure are typically spliced together with bolted connections. Plug-on connections are used extensively in residential, commercial, and industrial applications. They can be found in many everyday electrical devices such as in switchgear. The design of the plug-on connection is relatively simple. The plug-on design allows to avoid many common connectivity problems, including those due to vibration and thermal cycling. A significant advantage of the plug-on connection is that it creates multiple current paths on each side of the busbar. Each of the fingers on a plug-on jaw provides an individual current path with an equal contact area.
