  2. Pedestal - Wikipedia

    en.wikipedia.org/wiki/Pedestal

    A pedestal (from French piédestal, from Italian piedistallo 'foot of a stall') or plinth is a support at the bottom of a statue, vase, column, or certain altars. Smaller pedestals, especially if round in shape, may be called socles .

  3. Substation - Wikipedia

    en.wikipedia.org/wiki/Substation

    Capacitor banks are used in substations to balance the lagging current draw from inductive loads (such as motors, transformers, and some industrial equipment) with their reactive load. [46] Additional capacitor capacity may be needed if dispersed generation (such as small diesel generators, rooftop photovoltaic solar panels , or wind turbines ...

  4. Single-line diagram - Wikipedia

    en.wikipedia.org/wiki/Single-line_diagram

    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.

  5. Paternoster Vents - Wikipedia

    en.wikipedia.org/wiki/Paternoster_Vents

    The sculpture was commissioned by Stanhope and Mitsubishi Estate, who jointly developed the Paternoster Square site, to provide ventilation for a subsurface electrical substation with four electricity transformers under Bishop’s Court on the west side of the development. Thomas Heatherwick's design reduces the physical mass of the structure ...

  6. Bushing (electrical) - Wikipedia

    en.wikipedia.org/wiki/Bushing_(electrical)

    In electric power, a bushing is a hollow electrical insulator that allows an electrical conductor to pass safely through a conducting barrier such as the case of a transformer or circuit breaker without making electrical contact with it.

  7. High-leg delta - Wikipedia

    en.wikipedia.org/wiki/High-leg_delta

    High-leg delta service is supplied in one of two ways. One is by a three-phase transformer (or three single-phase transformers), having four wires coming out of the secondary, the three phases, plus a neutral connected as a center-tap on one of the windings. Another method (the open delta configuration) requires two transformers.

  8. Ring main unit - Wikipedia

    en.wikipedia.org/wiki/Ring_main_unit

    It includes in one unit two switches that can connect the load to either or both main conductors, and a fusible switch or circuit breaker and switch that feed a distribution transformer. [1] The metal enclosed unit connects to the transformer either through a bus throat of standardized dimensions, or else through cables and is usually installed ...

  9. Autotransformer - Wikipedia

    en.wikipedia.org/wiki/Autotransformer

    In electrical engineering, an autotransformer is an electrical transformer with only one winding. The "auto" (Greek for "self") prefix refers to the single coil acting alone. In an autotransformer, portions of the same winding act as both the primary winding and secondary winding sides of the transformer. In contrast, an ordinary transformer ...
