An electrical bus bar is defined as a conductor or a group of conductor used for collecting electric power from the incoming feeders and distributes them to the outgoing feeders. In other words, it is a type of electrical junction in which all the incoming and outgoing electrical current meets. Thus, the electrical bus bar collects the electric power at one location.A busbar is a rigid conductor used for connecting together several circuits. The system for monitoring partial discharge is connected in parallel with a busbar between a generator and an electric network. A busbar is a metal strip in a distribution box that provides one connection point for all the circuits.
