  2. Load (computing) - Wikipedia

    en.wikipedia.org/wiki/Load_(computing)

    htop displaying a significant computing load (top right: Load average:) In UNIX computing, the system load is a measure of the amount of computational work that a computer system performs. The load average represents the average system load over a period of time. It conventionally appears in the form of three numbers which represent the system ...

  3. Full load hour - Wikipedia

    en.wikipedia.org/wiki/Full_load_hour

    Full Load hour is a measure of the degree of utilisation of a technical system. [1] [2] [3] Full load hours refer to the time for which a plant would have to be operated at nominal power in order to convert the same amount of electrical work as the plant has actually converted within a defined period of time, during which breaks in operation or partial load operation can also occur.

  4. Prospective short-circuit current - Wikipedia

    en.wikipedia.org/wiki/Prospective_short-circuit...

    For simple radial distribution systems with only a few elements, hand calculation is feasible, but computer software is generally used for more complex systems. Where rotating machines (generators and motors) are present in the system, the time-varying effect of their contribution to a short circuit may be evaluated.

  5. Power factor - Wikipedia

    en.wikipedia.org/wiki/Power_factor

    A leading power factor signifies that the load is capacitive, as the load supplies reactive power, and therefore the reactive component is negative as reactive power is being supplied to the circuit. If θ is the phase angle between the current and voltage, then the power factor is equal to the cosine of the angle, cos ⁡ θ {\displaystyle ...

  6. Per-unit system - Wikipedia

    en.wikipedia.org/wiki/Per-unit_system

    In the power systems analysis field of electrical engineering, a per-unit system is the expression of system quantities as fractions of a defined base unit quantity. . Calculations are simplified because quantities expressed as per-unit do not change when they are referred from one side of a transformer to t

  7. Control panel (software) - Wikipedia

    en.wikipedia.org/wiki/Control_panel_(software)

    Many computer user interfaces use a control panel metaphor to give the user control of software and hardware features. The control panel consists of multiple settings including display settings, network settings, user account settings, and hardware settings. Control panels are also used by web applications for easy graphical configuration. [1]

  8. Load regulation - Wikipedia

    en.wikipedia.org/wiki/Load_regulation

    is the voltage at maximum load. The maximum load is the one that draws the greatest current, i.e. the lowest specified load resistance (never short circuit); is the voltage at minimum load. The minimum load is the one that draws the least current, i.e. the highest specified load resistance (possibly open circuit for some types of linear ...

  9. Power supply unit (computer) - Wikipedia

    en.wikipedia.org/wiki/Power_supply_unit_(computer)

    When a computer is in ACPI S3 sleep mode, only +5 V SB rail is used. There are two basic differences between AT and ATX power supplies: the connectors that provide power to the motherboard, and the soft switch. In ATX-style systems, the front-panel power switch provides only a control signal to the power supply and does not switch the mains AC ...
