Question: An industrial facility is being penalized by its utility provider for a low power factor. Which of the following is the most common method to improve the power factor in such a facility?
Answer options:
- Installing larger transformers ✅ Adding shunt capacitors
- Increasing the supply voltage
- Replacing all squirrel cage motors with synchronous motors
Correct answer: Adding shunt capacitors
Explanation: Inductive loads (like motors) cause a lagging power factor. Shunt capacitors draw leading reactive power, which compensates for the lagging reactive power, thereby improving the overall power factor of the facility economically. While synchronous motors can also improve power factor, it's not always practical to replace all existing motors.
