How to calculate power consumption of an unbalanced 3 phase circuit?
Power consumption of an unbalanced three phase circuit can be calculated by one of several methods. If the current and power factor of each phase of a delta circuit are known then each phase can be treated as a single phase circuit. The power of each phase can be readily calculated and the net power is the sum of the separately-determined values.
How do you calculate power in an unbalanced 3 phase Wye Circuit?
Calculating Power in Unbalanced Three Phase Wye Circuits 4B1. General A viable method to determine the total power of an unbalanced three phase wye circuit is to treat the circuit as a combination of three single phase circuits.

How is total power determined in an unbalanced 3 phase delta circuit?
General Much as with a wye circuit, total power in an unbalanced three phase delta circuit can be determined by treating the circuit as a combination of three single phase circuits. The power of each of the three phases is separately determined and the total of the three becomes the three phase power of the circuit.
Is a 3 phase circuit balanced or unbalanced?
In general three phase loads are considered either “balanced” or “unbalanced”. A three phase circuit is considered balanced if the voltages, currents and power factors in all three phases are identical.
