  2. Zigzag transformer - Wikipedia

    en.wikipedia.org/wiki/Zigzag_transformer

    A conventional six-winding, grounding transformer or zigzag bank, [1] with the same winding and core quantity as a conventional three-phase transformer, can also be used in zigzag winding connection. In all cases the first coil on each zigzag winding core is connected contrariwise to the second coil on the next core.

  3. 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 ...

  4. Flyback transformer - Wikipedia

    en.wikipedia.org/wiki/Flyback_transformer

    Unlike conventional transformers, a flyback transformer is not fed with a signal of the same waveshape as the intended output current. A convenient side effect of such a transformer is the considerable energy that is available in its magnetic circuit. This can be exploited using extra windings to provide power to operate other parts of the ...

  5. Pad-mounted transformer - Wikipedia

    en.wikipedia.org/wiki/Pad-mounted_transformer

    Single- and three-phase pad-mounted transformers are used in underground industrial and residential power distribution systems, where there is a need for safe, reliable, and aesthetically appealing transformer design. Their enclosed construction allows the installation of pad-mount transformers in public areas without protective fencing.

  6. Toroidal inductors and transformers - Wikipedia

    en.wikipedia.org/wiki/Toroidal_inductors_and...

    Toroidal inductors and transformers are inductors and transformers which use magnetic cores with a toroidal (ring or donut) shape. They are passive electronic components , consisting of a circular ring or donut shaped magnetic core of ferromagnetic material such as laminated iron , iron powder, or ferrite , around which wire is wound.

  8. Modulation transformer - Wikipedia

    en.wikipedia.org/wiki/Modulation_transformer

    The primary winding of a modulation transformer is fed by an audio amplifier that has about 1/2 of the rated input power of the transmitter's final amplifier stage. The secondary winding is in series with the power supply of that final radio-frequency amplifier stage, thereby allowing the audio signal to lower and raise the instantaneous DC ...

  9. Hydro-Québec's electricity transmission system - Wikipedia

    en.wikipedia.org/wiki/Hydro-Québec's_electricity...

    The two major and three minor NERC interconnections, and the nine NERC Regional Reliability Councils. 735 kV substation near the Robert-Bourassa generating station. Hydro-Québec's electricity transmission system (also known as the Quebec interconnection) is an international electric power transmission system centred in Quebec, Canada.
