An AC motor is started and produces 25 horsepower when running at rated speed and load. Neglecting power factor considerations, how much will the kW meter reading increase for the sole generator providing power?
⢠Relationship between horsepower (HP) and kilowatts (kW) ⢠Unit conversion factor between HP and kW (mechanical horsepower) ⢠Effect of neglecting power factor on real power calculation
⢠How do you convert 25 horsepower into kilowatts using the standard HP-to-kW conversion factor? ⢠Once you have the motor power in kW, what does that tell you about how much additional real power the generator must supply? ⢠Are there any extra losses or factors mentioned in the question that should change the simple HP-to-kW conversion?
⢠Use the correct conversion: 1 HP â 0.746 kW (mechanical horsepower). ⢠Confirm you are finding the increase in kW reading, not the total generator output. ⢠Verify that neglecting power factor means you treat the kW reading as matching the mechanical power (after conversion) without additional reactive power considerations.
