EEE Formula: Power

Power:

1 kW = 1.341Hp

1Hp = 0.746 kW 

Hp= Horsepower, kW = Kilowatt

VA = VxI

Watt = VICosφ

VAR = VISinφ

Single Phase:

kVA = VxI,  kW = VxIxPF, I = kWx1000/VxPF,  V = kWx1000/IxPF

Three Phase:

kVA =√3x VxI/1000,  kW =  √3xVxIxPF/1000,  (P = 1.732VICosφ)

V_L = √3xV_P ,  V_P = V_L, /√3,  I_L = I_P  (Star Connection)

I_L = √3xI_P,     I_P = I_L /√3_,   V_L =V_P  (Delta Connection)
