WebUse this formula to estimate motor horsepower. Horsepower (hp) = Voltage x Amperage x % EFF x power factor x 1.73/746. Where: Voltage is the average of the three voltages measured: (A-B + A-C + B-C)/3. Amperage is the average current of the three phase measured: (A+B+C)/3 % EFF is motor efficiency per motor nameplate. Power factor is … WebExample over 200 horsepower: Horsepower = 275, Voltage = 460 Chart value of 1.2A/HP multiplied by 275 HP = 330A. 330A X 1.25 = 412.5A. Closest standard current transformer ratio is 400/5. For single phase motors, determine full load current from the nameplate rating. Multiply by 1.25 to get the approximate CT rating, as shown above.
