Determining Electric Motor Load and Efficiency - Energy

The relationship is shown in Equation 3. Equation 1 Equation 2 Equation 3 P i = V x I x PF x √3 1000 Where: P i = Three-phase power in kW V = RMS voltage, mean line-to-line of 3 phases I = RMS current, mean of 3 phases PF = Power factor as a decimal Where: P ir = Input power at full-rated load in kW hp = Nameplate rated horsepower η ................
