  2. Power factor - Wikipedia

    en.wikipedia.org/wiki/Power_factor

    In electrical engineering, the power factor of an AC power system is defined as the ratio of the real power absorbed by the load to the apparent power flowing in the circuit. . Real power is the average of the instantaneous product of voltage and current and represents the capacity of the electricity for performing

  3. AC power - Wikipedia

    en.wikipedia.org/wiki/AC_power

    For instance, a power factor of 0.68 means that only 68 percent of the total current supplied (in magnitude) is actually doing work; the remaining current does no work at the load. Power Factor is very important in Power sector substations. Form the national grid the sub sectors are required to have minimum amount of power factor.

  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 ...

    Measurable dependent electrical quantities comprise: Inductance; Capacitance; Electrical impedance defined as vector sum of electrical resistance and electrical reactance; Electrical admittance, the reciprocal of electrical impedance; Phase between current and voltage and related power factor; Electrical spectral density; Electrical phase noise

  6. Zero power factor curve - Wikipedia

    en.wikipedia.org/wiki/Zero_power_factor_curve

    The zero power factor curve (also zero power factor characteristic, ZPF, ZPFC) of a synchronous generator is a plot of the output voltage as a function of the excitation current or field using a zero power factor (purely inductive) load that corresponds to rated voltage at rated current (1 p.u.).

    The plotted line represents the variation of instantaneous voltage (or current) with respect to time. This cycle repeats with a frequency that depends on the power system. 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 ...

    Electric power is the rate of transfer of electrical energy within a circuit.Its SI unit is the watt, the general unit of power, defined as one joule per second.Standard prefixes apply to watts as with other SI units: thousands, millions and billions of watts are called kilowatts, megawatts and gigawatts respectively.
