Busbar loop inductance
WebIn electric power distribution, a busbar (also bus bar) is a metallic strip or bar, typically housed inside switchgear, panel boards, and busway enclosures for local high current power distribution. They are also used … WebJan 21, 2024 · According to the electromagnetic field theory, the stray inductance of the laminated busbar includes two parts: self-inductance and mutual inductance. Self-inductance can be divided into internal inductance and external inductance. The internal inductance is generated by the leakage flux commutation inside the conductor.
