Understanding Power Factor Correction

What is power factor correction?

• Power factor correction is the process of improving the power factor in electrical systems to enhance efficiency and reduce energy losses.

• A process to convert AC power to DC power.

• A technique to reduce electrical resistance.

• A method to increase voltage in a circuit.

Why is the power factor important in electricity?

• The power factor is only related to the voltage level.

• The power factor is only relevant for large industrial machines.

• The power factor does not affect the electricity bill.

• The power factor is important because it affects energy efficiency and costs.

How can we improve the power factor in a circuit?

• Add load resistance in the circuit.

• Use an inductor to improve the power factor.

• Use a capacitor or synchronous condenser for power factor correction.

• Reduce the supply voltage to the circuit.

What happens if the power factor is low?

• A low power factor has no effect on costs.

• A low power factor increases energy efficiency.

• A low power factor causes inefficiency, higher energy costs, and potential penalties.

• A low power factor guarantees better performance.

Can you provide an example of power factor correction?

• Using a transformer to increase voltage levels

• Replacing all motors with smaller ones

• An example of power factor correction is installing capacitor banks in industrial facilities to reduce lagging power factor caused by large motors.

• Installing solar panels to generate electricity
