  2. Backfeeding - Wikipedia

    en.wikipedia.org/wiki/Backfeeding

    Backfeeding. Backfeeding is the flow of electric power in the direction reverse to that of the generally understood or typical flow of power. Depending on the source of the power, this reverse flow may be intentional or unintentional. If not prevented (in the case of unintentional backfeeding) or properly performed (in cases of intentional ...

  3. Breaking capacity - Wikipedia

    en.wikipedia.org/wiki/Breaking_capacity

    Breaking capacity. Breaking capacity or interrupting rating [1] [2] is the current that a fuse, circuit breaker, or other electrical apparatus is able to interrupt without being destroyed or causing an electric arc with unacceptable duration. The prospective short-circuit current that can occur under short circuit conditions should not exceed ...

  4. Electronic symbol - Wikipedia

    en.wikipedia.org/wiki/Electronic_symbol

    Electronic symbol. An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may vary from country to country ...

  5. Switchgear - Wikipedia

    en.wikipedia.org/wiki/Switchgear

    This circuit breaker uses both SF 6 and air as insulation. In an electric power system, a switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream.

  6. Electrical substation - Wikipedia

    en.wikipedia.org/wiki/Electrical_substation

    A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels.

  7. Transformer - Wikipedia

    en.wikipedia.org/wiki/Transformer

    Transformer. An O-core transformer consisting of two coils of copper wire wrapped around a magnetic core. 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 ...

  8. Electronic circuit - Wikipedia

    en.wikipedia.org/wiki/Electronic_circuit

    An electronic circuit is composed of individual electronic components, such as resistors, transistors, capacitors, inductors and diodes, connected by conductive wires or traces through which electric current can flow. It is a type of electrical circuit. For a circuit to be referred to as electronic, rather than electrical, generally at least ...

  9. Smart grid - Wikipedia

    en.wikipedia.org/wiki/Smart_grid

    The smart grid is an enhancement of the 20th century electrical grid, using two-way communications and distributed so-called intelligent devices. [1] Two-way flows of electricity and information could improve the delivery network. Research is mainly focused on three systems of a smart grid – the infrastructure system, the management system ...
