Some common three phase power equations can be expressed as
Real Power
Wapplied = 31/2 U I PF / 1000 (1)
where
Wapplied = real power (Kilowatts)
U = voltage (volts)
I = current (Amps)
PF = power factor - 0.7 - 0.95
Total Power
W = 31/2 U I / 1000 (2)
Brake Horsepower
WBHP = 31/2 U I PF μ / 746 (3)
where
WBHP = brake horse power (hp)
μ = device efficiency
