Question: A facility installs a capacitor bank for power factor correction. After installation, the overall plant power factor improves from 0.7 to 0.9 lagging. Which of the following is a direct benefit of this improvement, specifically for the facility's internal electrical system?
Answer options:
- Decreased utility energy charges. ✅ Reduced voltage drop in internal feeders.
- Elimination of harmonic currents.
- Increased available fault current.
Correct answer: Reduced voltage drop in internal feeders.
Explanation: Improving the power factor reduces the total current flowing through the facility's internal feeders for the same amount of active power delivered. Lower current results in lower IR voltage drops along the conductors, thus improving voltage regulation at the load end.
