Three-Phase Power
P = sqrt(3) x V x I x PF
What it means
Real power in a three-phase system. Rearranged, it estimates motor full-load current - the value compared with clamp-meter readings.
Variables
- P = Real power (watts (W))
- V = Line voltage (volts (V))
- I = Line current (amperes (A))
- PF = Power factor (0 to 1)
