Single phase power equations:

Real Power

W_applied = U I PF / 1000 (1)

where

W_applied = real power (kilowatts, kW)

U = voltage (volts, V)

I = current (amps, A)

PF = power factor - 0.7 - 0.95

Total Power

W = U I / 1000 (2)

Brake Horsepower

W_BHP = U I PF μ / 746 (3)

where

W_BHP = brake horsepower (hp)

μ = device efficiency
