It is the total conductor used to transmit electric energy in power stations or substations. Through it, the electric energy output by the generator, transformer or rectifier is transmitted to each user or other substation.

[0003] In the power system, the busbar connects each current-carrying branch circuit in the power distribution device together, playing the role of collecting, distributing and transmitting electric energy.
