A smaller type of isolated-phase bus is manufactured for direct-current circuits; this may be used in the field circuit of a generator. Currently, the isolated-phase bus world record current is 52,000 A, for bus manufactured by Alstom Power (since 2015 General Electric Power) and installed at the Civaux Nuclear Power Plant, in 1997.

In 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 to connect high voltage equipment at electrical switchyards, and low-voltage equipment in battery banks .
Enclosure comparison with normal wiring & with busbar system. Electrical busbar systems [1] (sometimes simply referred to as busbar systems) are a modular approach to electrical wiring, where instead of a standard cable wiring to every single electrical device, the electrical devices are mounted onto an adapter which is directly fitted to a current carrying busbar.
The slack bus is the only bus for which the system reference phase angle is defined. From this, the various angular differences can be calculated in the power flow equations. If a slack bus is not specified, then a generator bus with maximum real power | | acts as the slack bus. A given scheme can involve more than one slack bus.
In power engineering, the power-flow study, or load-flow study, is a numerical analysis of the flow of electric power in an interconnected system. A power-flow study usually uses simplified notations such as a one-line diagram and per-unit system, and focuses on various aspects of AC power parameters, such as Voltage, voltage angles, real power and reactive power.
The $1 billion in annual revenue from the tolls would help fund critical and long overdue improvements to the city’s bus and subway systems, which run 24/7 and move more than 4.5 million people ...
Each bus in a real power system is usually connected to only a few other buses through the transmission lines. [1] The nodal admittance matrix is used in the formulation of the power flow problem . Construction from a single line diagram
