    CALCULATION OF REAL POWER IN A THREE-PHASE SYSTEM

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

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

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

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