    CALCULATION OF TOTAL POWER IN A THREE PHASE SYSTEM

    The following formula calculates total power in a three-phase system based on KW and KVAr or voltage and current. Input load KW and load KVAr into Calculator-1 or line-to-line voltage (kV) and current (Amp) into Calculator-2 to calculate Total Power (kVA). Calculator-1 will also calculate the power factor based on the load input.

    Calculator-1

    Known variables: Real Power and Reactive Power

    Calculator-2

    Known variables: Line-Line Voltage and Line Current

    Input Real Power (KW):    Input VLL (kV):  
    Input Reactive Power (kVAr):    Input I (Amp): 
    Total Power (KVA):    Total Power (kVA): 
    Power Factor (PF):
