  2. Load bank - Wikipedia

    en.wikipedia.org/wiki/Load_bank

    A load bank is a piece of electrical test equipment used to simulate an electrical load, to test an electric power source without connecting it to its normal operating load. [ 1 ] [ 2 ] During testing, adjustment, calibration, or verification procedures, a load bank is connected to the output of a power source, such as an electric generator ...

    en.wikipedia.org/wiki/Diesel_generator

    Set sizes range from 8 to 30-kW (also 8 to 30-kVA single phase) for homes, small shops, and offices, with the larger industrial generators from 8-kW (11 kVA) up to 2,000-kW (2,500-kVA three phase) used for office complexes, factories, and other industrial facilities. A 2,000-kW set can be housed in a 40 ft (12 m) ISO container with a fuel tank ...

  4. Kill A Watt - Wikipedia

    en.wikipedia.org/wiki/Kill_A_Watt

    The power setting displays instantaneous power, and the kilowatt-hour setting displays energy consumed since last reset. When electricity is disconnected, the P4400's measurements and meters are reset. [6] To reset Kill A Watt models that store values, press Volt and Amp together, or press the Reset key in some models.

    en.wikipedia.org/wiki/Uninterruptible_power_supply

    The main 50/60 Hz transformer used to convert between line voltage and battery voltage needs to provide two slightly different turns ratios: One to convert the battery output voltage (typically a multiple of 12 V) to line voltage, and a second one to convert the line voltage to a slightly higher battery charging voltage (such as a multiple of ...

  6. Electric generator - Wikipedia

    en.wikipedia.org/wiki/Electric_generator

    A magnetohydrodynamic generator directly extracts electric power from moving hot gases through a magnetic field, without the use of rotating electromagnetic machinery. MHD generators were originally developed because the output of a plasma MHD generator is a flame, well able to heat the boilers of a steam power plant. The first practical design ...

  7. Watt - Wikipedia

    en.wikipedia.org/wiki/Watt

    The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m 2 ⋅s −3. [1] [2] [3] It is used to quantify the rate of energy transfer.

    Nearly half of all women have "dense breasts"—yet countless don't find out until later in life. Dense breasts have more fibrous and glandular tissue relative to fat tissue in the breast.

  9. Kilowatt-hour - Wikipedia

    en.wikipedia.org/wiki/Kilowatt-hour

    In the case of devices that output a different voltage than the battery, it is the battery voltage (typically 3.7 V for Li-ion) that must be used to calculate rather than the device output (for example, usually 5.0 V for USB portable chargers). This results in a 500 mA USB device running for about 3.7 hours on a 2,500 mAh battery, not five hours.
