CALCULATION OF TOTAL POWER IN A SINGLE PHASE SYSTEM
The following formula calculates total power in a single phase system based on KW and KVAr or voltage and current. Input load KW and load KVAr into Calculator-1 or line-to-neutral 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-Neutral Voltage and Line Current
