Question: What is the primary benefit of improving the power factor in an industrial electrical system?
Answer options:
- Increased generator speed ✅ Reduced overall reactive power demand from the utility
- Higher operating ambient temperature for equipment
- Elimination of all harmonics
Correct answer: Reduced overall reactive power demand from the utility
Explanation: The primary benefit of improving the power factor by adding capacitors is to reduce the amount of reactive power that needs to be supplied by the utility, thus reducing utility charges and freeing up capacity in the electrical distribution system. It does not affect generator speed, it reduces conductor heating, and it does not eliminate harmonics.
