Question: An electrician is troubleshooting a facility with a significantly low power factor. What is a common negative consequence of a low power factor that affects the electrical distribution system?
Answer options:
- Increased voltage stability
- Reduced heat dissipation in conductors ✅ Higher utility bills due to kilovar charges
- Decreased demand on transformers
Correct answer: Higher utility bills due to kilovar charges
Explanation: A low power factor means more reactive power is flowing, which increases the apparent power. Utilities often charge for kilovar demand or penalize for low power factor, leading to higher electricity bills. It also leads to increased current, higher I²R losses in conductors (increased heat), and higher demand on transformers.
