  2. Distribution transformer - Wikipedia

    en.wikipedia.org/wiki/Distribution_transformer

    Transformers designed for below-grade installation can be designed for periodic submersion in water. [14] Distribution transformers may include an off-load tap changer, which slightly adjusts the ratio between primary and secondary voltage to bring the customer's voltage within the desired range on long or heavily loaded lines.

  3. Common Information Model (electricity) - Wikipedia

    en.wikipedia.org/wiki/Common_Information_Model...

    The Common Information Model (CIM) is an electric power transmission and distribution standard developed by the electric power industry.It aims to allow application software to exchange information about an electrical network. [1]

  4. Delta-wye transformer - Wikipedia

    en.wikipedia.org/wiki/Delta-wye_transformer

    A delta-wye transformer is a type of three-phase electric power transformer design that employs delta-connected windings on its primary and wye/star connected windings on its secondary. A neutral wire can be provided on wye output side. It can be a single three-phase transformer, or built from three independent single-phase units.

  5. Buck–boost transformer - Wikipedia

    en.wikipedia.org/wiki/Buck–boost_transformer

    Buck–boost transformers can be used to power low voltage circuits including control, lighting circuits, or applications that require 12, 16, 24, 32 or 48 volts, consistent with the design's secondaries. The transformer is connected as an isolating transformer and the nameplate kVA rating is the transformer’s capacity. [2]

  6. Load profile - Wikipedia

    en.wikipedia.org/wiki/Load_Profile

    The power transformer or battery-to-grid are critical aspects of power distribution and sizing and modelling of batteries or transformers depends on the load profile. [1] The factory specification of transformers for the optimization of load losses versus no-load losses is dependent directly on the characteristics of the load profile that the ...

  7. Spot network substation - Wikipedia

    en.wikipedia.org/wiki/Spot_Network_Substation

    The FedExForum in Memphis has a network of four primary transformers connected to the same secondary bus. In some arrangements with four transformers, any of the transformers can carry all of its connected loads. The Toronto Pearson International Airport is electrically fed by four grid feeders, each capable of carrying the entire 20+ MW load. [4]

  8. Pad-mounted transformer - Wikipedia

    en.wikipedia.org/wiki/Pad-mounted_transformer

    Padmount transformers are used with underground electric power distribution lines at service drops to step down the primary voltage on the line to the lower secondary voltage supplied to utility customers. A single transformer may serve one large building or many homes.

  9. 25 kV AC railway electrification - Wikipedia

    en.wikipedia.org/wiki/25_kV_AC_railway...

    In this system, the current is mainly carried between the overhead line and a feeder transmission line instead of the rail. The overhead line (3) and feeder (5) are on opposite phases so the voltage between them is 50 kV, while the voltage between the overhead line (3) and the running rails (4) remains at 25 kV. Periodic autotransformers (9 ...
