    en.wikipedia.org/wiki/Single-line_diagram

    A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.

    the parts might never be used; the parts might not be stored properly, leading to defects; maintaining inventory of spare parts has associated costs; parts may not be available when needed from a supplier; But without the spare part on hand, a company's customer satisfaction levels could drop if a customer has to wait too long for their item to ...

  5. 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 ...

    en.wikipedia.org/wiki/Voltage_transformer

    The circuit diagram for a simple capacitor voltage transformer In its most basic form, the device consists of three parts: a two capacitor voltage divider across which the transmission line, an inductive element to tune the device to the line frequency, and a voltage transformer to isolate and further step down the voltage for metering devices ...

  8. Amorphous metal transformer - Wikipedia

    en.wikipedia.org/wiki/Amorphous_metal_transformer

    An amorphous metal transformer (AMT) is a type of energy efficient transformer found on electric grids. [1] The magnetic core of this transformer is made with a ferromagnetic amorphous metal . The typical material ( Metglas ) is an alloy of iron with boron , silicon , and phosphorus in the form of thin (e.g. 25 μm) foils rapidly cooled from melt.

  9. Tap changer - Wikipedia

    en.wikipedia.org/wiki/Tap_changer

    However, a transformer may include a tap changer on each winding if there are advantages to do so. For example, in power distribution networks, a large step-down transformer may have an off-load tap changer on the primary winding and an on load automatic tap changer on the secondary winding or windings. The high voltage tap is set to match long ...
