  2. Isolated-phase bus - Wikipedia

    en.wikipedia.org/wiki/Isolated-phase_bus

    In electrical engineering, isolated-phase bus (IPB), also known as phase-isolated bus (PIB) in some countries, is a method of construction for circuits carrying very large currents, typically between a generator and its step-up transformer in a steam or large hydroelectric power plant. Isolated phase bus during installation at the Bui Dam Ghana ...

  4. Busbar - Wikipedia

    en.wikipedia.org/wiki/Busbar

    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 .

  5. Electrical busbar system - Wikipedia

    en.wikipedia.org/wiki/Electrical_busbar_system

    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.

    A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.

  8. Isolation transformer - Wikipedia

    en.wikipedia.org/wiki/Isolation_transformer

    Even if an isolation transformer is used, hazardous voltages may still be present between components of the isolated device. Thus it is still possible for an operator to be exposed to lethal voltages by touching multiple elements in the circuit. An isolation transformer provides maximum protection when the device is ungrounded.
