  2. Load bank - Wikipedia

    en.wikipedia.org/wiki/Load_bank

    An inductive load consists of an iron-core reactive element which, when used in conjunction with a resistive load bank, creates a lagging power factor load. Typically, the inductive load will be rated at a numeric value 75% that of the corresponding resistive load such that when applied together a resultant 0.8 power factor load is provided.

  3. Liquid rheostat - Wikipedia

    en.wikipedia.org/wiki/Liquid_rheostat

    Railways commonly used salt water load banks in the 1950s to test the output power of diesel-electric locomotives. [3] They were subsequently replaced by specially designed resistive load banks. Some early three-phase AC electric locomotives also used liquid rheostats for starting up the motors and balancing load between multiple locomotives. [4]

  4. Dummy load - Wikipedia

    en.wikipedia.org/wiki/Dummy_load

    An electronic load (or e-load) is a device or assembly that simulates loading on an electronic circuit. It is used as substitute for a conventional ohmic load resistor. Electronic loads with 800W and 4200W from Höcherl & Hackl. As counterpart to a current source, the electronic load is a current sink. When loading a current source with a fixed ...

    Control of D.C. electromagnetic loads having economy resistors in the circuit: 60947-5-1 DC-20: Connecting and disconnecting under no-load conditions: 60947-5-1 DC-21: Switching of resistive loads, including moderate overloads: 60947-5-1 DC-22: Switching of mixed resistive and inductive loads, including moderate overloads (i.e. shunt motors ...

  6. Inrush current - Wikipedia

    en.wikipedia.org/wiki/Inrush_current

    Any electrical load that contains a substantial component of metallic resistive heating elements, such as an electric kiln or a bank of tungsten-filament incandescent bulbs, will draw a high current until the metallic element reaches operating temperature. For example, wall switches intended to control incandescent lamps will have a "T" rating ...

  7. Programmable load - Wikipedia

    en.wikipedia.org/wiki/Programmable_load

    A programmable load is a type of test equipment or instrument which emulates DC or AC resistance loads normally required to perform functional tests of batteries, ...

  8. Voltage control and reactive power management - Wikipedia

    en.wikipedia.org/wiki/Voltage_control_and...

    Electrical loads usually absorb the reactive power, [7] with the power factor for typical appliances ranging from 0.65 (household equipment with electrical motors, like a washing machine) to 1.0 (purely resistive loads like incandescent lamps). [8]

  9. Voltage optimisation - Wikipedia

    en.wikipedia.org/wiki/Voltage_optimisation

    A reduction in voltage does not affect the energy used by the domestic appliances which use resistive loads except in devices such as kettles and toasters which will take longer to do their job due to atmospheric losses. The main commercial benefit when installing VO units, is on inductive loads, like motors which run pumps, fans and the like.
