# Calculation of 3 phase current in \$\$\$?

How to calculate 3 phase current with average 40amp, power=22kw, Voltage= 415Vac ??
1kwh= \$0.20

Answer:
Three phase power is calculated from Watts = Volts x Amps X Square root of 3 X Power factor. If power is 22kw in your example, power factor must be 0.77.

Cost is Power in kW X Hours of operation X cost for 1kwh.
You have given a power value. If this is a motor and that is the maximum power output of the motor then it has no bearing on running cost. If this is the input power of something then its simply 22 X 0.22 = \$4.84 per hour to operate.

You may want to clarify what your numbers are.
