    CALCULATION OF REAL POWER IN A SINGLE-PHASE SYSTEM

    The following calculators compute real power in a single-phase system based on Kvar and KVA or voltage, current, and power factor.

    Calculator-1
    Input the system line-to-neutral voltage, line current, and power factor angle (degrees) into Calculator-1 to compute single-phase real power, reactive power, and total power as well as the power factor.

    Calculator-2
    Input the system line-neutral voltage, line current, and power factor into Calculator-2 to compute single-phase real power, reactive power, and total power as well as the power factor angle.

    Calculator-3
    Input the single-phase total power, and reactive power into Calculator-3 to compute single-phase real power, power factor and power factor angle (degrees).
