Three Phase Power Formula
The following formula is used to calculate the Three Phase Power.
P = V*I*PF*SQRT(3)
- Where P is the Three Phase Power (watts)
- V is the voltage (amps)
- I is the current (amps)
- PF is the power factor
How to Calculate Three Phase Power?
The following example problems outline how to calculate Three Phase Power.
Example Problem #1
- First, determine the voltage (amps). In this example, the voltage (amps) is determined to be 23 .
- Next, determine the current (amps). For this problem, the current (amps) is measured to be 20 .
- Next, determine the power factor. In this case, the power factor is found to be 15.
- Finally, calculate the Three Phase Power using the formula above:
P = V*I*PF*SQRT(3)
Inserting the values from above and solving yields:
P = 23*20*15*SQRT(3) = 11,951.15 (watts)
Example Problem #2
Using the same method as above, determine the variables required by the formula. For this example problem, these are:
voltage (amps) = 10
current (amps) = 4
power factor = 8
Enter these given values into the calculator or above yields:
P = 10*4*8*SQRT(3) = 554.25 (watts)
