  2. Electrical load - Wikipedia

    en.wikipedia.org/wiki/Electrical_load

    An electrical load is an electrical component or portion of a circuit that consumes (active) electric power, [1] [2] such as electrical appliances and lights inside the home. The term may also refer to the power consumed by a circuit. This is opposed to a power supply source, such as a battery or generator, which provides power. [2]

  3. Power-flow study - Wikipedia

    en.wikipedia.org/wiki/Power-flow_study

    In power engineering, the power-flow study, or load-flow study, is a numerical analysis of the flow of electric power in an interconnected system. A power-flow study usually uses simplified notations such as a one-line diagram and per-unit system, and focuses on various aspects of AC power parameters, such as Voltage, voltage angles, real power and reactive power.

  4. Load factor (electrical) - Wikipedia

    en.wikipedia.org/wiki/Load_factor_(electrical)

    In electrical engineering the load factor is defined as the average load divided by the peak load in a specified time period. [1] It is a measure of the utilization rate, or efficiency of electrical energy usage; a high load factor indicates that load is using the electric system more efficiently, whereas consumers or generators that underutilize the electric distribution will have a low load ...

  5. 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

  6. Miscellaneous electric load - Wikipedia

    en.wikipedia.org/wiki/Miscellaneous_electric_load

    However, recent advances in three technology areas is fostering next generation energy management solutions including a new pathway for cost-effective MELs monitoring and control solutions: 1) environmental and electrical sensor technologies, 2) cloud computing capacity and access to support AI and machine learning, and 3) wide acceptance of ...

  7. Power system simulation - Wikipedia

    en.wikipedia.org/wiki/Power_system_simulation

    Load-flow calculation is also the basis of all further network studies, such as motor start-up or investigation of scheduled or unscheduled outages of equipment within the outage simulation. Especially when investigating motor start-up, [ 2 ] the load-flow calculation results give helpful hints, for example, of whether the motor can be started ...

  8. Mathematics of three-phase electric power - Wikipedia

    en.wikipedia.org/wiki/Mathematics_of_three-phase...

    In electrical engineering, three-phase electric power systems have at least three conductors carrying alternating voltages that are offset in time by one-third of the period. A three-phase system may be arranged in delta (∆) or star (Y) (also denoted as wye in some areas, as symbolically it is similar to the letter 'Y').

  9. Factor of safety - Wikipedia

    en.wikipedia.org/wiki/Factor_of_safety

    In engineering, a factor of safety (FoS) or safety factor (SF) expresses how much stronger a system is than it needs to be for an intended load.Safety factors are often calculated using detailed analysis because comprehensive testing is impractical on many projects, such as bridges and buildings, but the structure's ability to carry a load must be determined to a reasonable accuracy.
