Electrician Red Seal · Question
A capacitor bank is being installed to improve the power factor of an industrial facility. Before installation, the facility has a lagging power factor of 0.75. After installing the capacitor bank, the overall power factor is improved to 0.95 lagging. What is the primary effect of this power factor correction on the facility's electrical system?
Improving the power factor reduces the apparent power (kVA) needed to deliver the same amount of real power (kW). This occurs because the capacitor bank supplie

Question: A capacitor bank is being installed to improve the power factor of an industrial facility. Before installation, the facility has a lagging power factor of 0.75. After installing the capacitor bank, the overall power factor is improved to 0.95 lagging. What is the primary effect of this power factor correction on the facility's electrical system?
Answer options: ✅ Decrease in total apparent power (kVA) drawn from the utility for the same real power (kW).
- Increase in the reactive power (kVAR) consumed by inductive loads.
- Significant voltage drop across the utility's distribution transformers.
- Reduction in the real power (kW) consumption of the facility.
Correct answer: Decrease in total apparent power (kVA) drawn from the utility for the same real power (kW).
Explanation: Improving the power factor reduces the apparent power (kVA) needed to deliver the same amount of real power (kW). This occurs because the capacitor bank supplies reactive power (kVAR) locally, reducing the reactive power demanded from the utility and thus decreasing the total current flowing from the utility for the same real power. This can also lead to reduced utility charges.
