  2. Buck–boost transformer - Wikipedia

    en.wikipedia.org/wiki/Buck–boost_transformer

    A buck–boost transformer is a type of transformer used to make adjustments to the voltage applied to alternating current equipment. [1] Buck–boost connections are used in several places such as uninterruptible power supply (UPS) units for computers and in the tanning bed industry. Buck–boost transformers can be used to power low voltage ...

  3. Transformer - Wikipedia

    en.wikipedia.org/wiki/Transformer

    Transformer. In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits. A varying current in any coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force (EMF) across ...

  4. Distribution Transformer Monitor - Wikipedia

    en.wikipedia.org/wiki/Distribution_Transformer...

    A Distribution Transformer Monitor (DTM) is a specialized hardware device that collects and measures information relative to electricity passing into and through a distribution transformer. The DTM is typically retrofitted onto pole top and pad mount transformers. A pole top (above ground) or pad mount (below ground) transformer commonly powers ...

  5. Single-wire earth return - Wikipedia

    en.wikipedia.org/wiki/Single-wire_earth_return

    Single-wire earth return (SWER) or single-wire ground return is a single-wire transmission line which supplies single-phase electric power from an electrical grid to remote areas at lowest cost. The earth (or sometimes a body of water) is used as the return path for the current, to avoid the need for a second wire (or neutral wire) to act as a ...

  6. Grounding transformer - Wikipedia

    en.wikipedia.org/wiki/Grounding_transformer

    A grounding transformer or earthing transformer is a type of auxiliary transformer used in three-phase electric power systems to provide a ground path to either an ungrounded wye or a delta-connected system. [1][2] Grounding transformers are part of an earthing system of the network. They let three-phase (delta connected) systems accommodate ...

  7. Electric power conversion - Wikipedia

    en.wikipedia.org/wiki/Electric_power_conversion

    Recloser. Protective relay. v. t. e. In electrical engineering, power conversion is the process of converting electric energy from one form to another. A power converter is an electrical device for converting electrical energy between alternating current (AC) and direct current (DC). It can also change the voltage or frequency of the current.

  8. Distribution transformer - Wikipedia

    en.wikipedia.org/wiki/Distribution_transformer

    A distribution transformer or service transformer provides a final voltage transformation in the electric power distribution system, stepping down the voltage used in the distribution lines to the level used by the customer. [1] The invention of a practical, efficient transformer made AC power distribution feasible; a system using distribution ...

  9. Impedance matching - Wikipedia

    en.wikipedia.org/wiki/Impedance_matching

    The power input to the transformer and output from the transformer is the same (except for conversion losses). The side with the lower voltage is at low impedance (because this has the lower number of turns), and the side with the higher voltage is at a higher impedance (as it has more turns in its coil).
