  2. Vector group - Wikipedia

    en.wikipedia.org/wiki/Vector_group

    For example, a transformer with a vector group of Dy1 has a delta-connected HV winding and a wye-connected LV winding. The phase angle of the LV winding lags the HV by 30 degrees. Note that the high-voltage (HV) side always comes before the low-voltage (LV) side, regardless of which is the primary winding.

    en.wikipedia.org/wiki/McGraw-Edison

    It made several acquisitions over the years, evolving into a manufacturer of electrical products. In 1952 McGraw Electric and the Pennsylvania Transformer Company merged, keeping the name of McGraw Electric. [2] Thomas A. Edison, Inc. was formed in 1910 as a reorganization of the Edison Manufacturing Co., which had its roots in the 19th century.

    IEC 61797 Transformers and inductors for use in telecommunication and electronic equipment – Main dimensions of coil formers; IEC 61800 Adjustable speed electrical power drive systems; IEC 61803 Determination of power losses in high-voltage direct current (HVDC) converter stations; IEC TS 61804 Function blocks (FB) for process control

  5. 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.

  6. Transformer types - Wikipedia

    en.wikipedia.org/wiki/Transformer_types

    A leakage transformer, also called a stray-field transformer, has a significantly higher leakage inductance than other transformers, sometimes increased by a magnetic bypass or shunt in its core between primary and secondary, which is sometimes adjustable with a set screw. This provides a transformer with an inherent current limitation due to ...

  7. 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 ...

  8. Quadrature booster - Wikipedia

    en.wikipedia.org/wiki/Quadrature_booster

    400 MVA 220/155 kV phase-shifting transformer.. A phase angle regulating transformer, phase angle regulator (PAR, American usage), phase-shifting transformer, phase shifter (West coast American usage), or quadrature booster (quad booster, British usage), is a specialised form of transformer used to control the flow of real power on three-phase electric transmission networks.

  9. HVDC converter station - Wikipedia

    en.wikipedia.org/wiki/HVDC_converter_station

    A single-phase, three-winding converter transformer. The converter transformers step up the voltage of the AC supply network. Using a star-to-delta or "wye-delta" connection of the transformer windings, the converter can operate with 12 pulses for each cycle in the AC supply, which eliminates numerous harmonic current components. The insulation ...
