A busbar is a strip or bar of copper, brass or aluminum that conducts electricity within a switchboard, a substation or a battery bank. Its purpose is to conduct a substantial current of electricity.
ABB's busbar protection is designed for phase-segregated short-circuit protection, control, and supervision of single busbars. The busbar protection relay is intended for use in high-impedance-based applications within utility substations and industrial power systems. The relay can also be utilized in restricted earth-fault and residual earth-fault applications for the protection of generators, motors, transformers and reactors.
