A busbar is a metallic bar in a switchgear panel used to carry electric power from incoming feeders and distributes to the outgoing feeders. In simple terms, busbar is a electrical junction where incoming and outgoing currents exchange.
Electrical Busbar consists the number of lines electrically, which are operating at the same voltage and frequencies. Generally, copper or aluminum conducting material is used in the construction of bus bars.
They are used either in the form of pipe or thin-walled tubes.
Purpose of Bus-bar
Bus bars are arranged in a different configurations, any particular arrangement of bus-bar is to achieve adequate operating flexibility, sufficient reliability and minimum cost.
The circuit breakers are arranged to get the maximum availability to plant operations.
Types of bus bars
Important bus-bar arrangements are discussed in this article. Based on the construction of the bus bar, they are divided as follows.
