  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. Electric power distribution - Wikipedia

    en.wikipedia.org/wiki/Electric_power_distribution

    Transformers step down transmission voltages, 35 kV or more, down to primary distribution voltages. These are medium voltage circuits, usually 600–35 000 V. [1] From the transformer, power goes to the busbar that can split the distribution power off in multiple directions. The bus distributes power to distribution lines, which fan out to ...

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

    It aims to allow application software to exchange information about an electrical network. [1] It has been officially adopted by the International Electrotechnical Commission (IEC). The CIM is currently maintained as a UML model. [2] It defines a common vocabulary and basic ontology. CIM models the network itself using the 'wires model'.

  5. 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 ...

  6. Split-phase electric power - Wikipedia

    en.wikipedia.org/wiki/Split-phase_electric_power

    [1] The system is common in North America for residential and light commercial applications. Two 120 V AC lines are supplied to the premises that are out of phase by 180 degrees with each other (when both measured with respect to the neutral), along with a common neutral. The neutral conductor is connected to ground at the transformer center tap.

  7. Transformer types - Wikipedia

    en.wikipedia.org/wiki/Transformer_types

    The two cylindrical metal cases fit into octal sockets; each one contains a 1:1 line transformer, the first is rated at 600 ohms, the second is rated at 15,000 ohms. On the far right is a DI unit; its 12:1 transformer (with yellow insulation) changes a high impedance unbalanced input to a low impedance balanced output.

  8. 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.
