4.2.2. Power Factor Correction (PFC)

Try these first

1. 1.

   What is power factor?

   Hint

   Think about the ratio of real power to apparent power.

2. 2.

   Name one method of Power Factor Correction.

   Hint

   Consider techniques used to improve efficiency.

3. 3.

   What does a low power factor indicate?

   • Inefficient use of electricity
   • High efficiency
   • Optimal energy usage

   Hint

   Think about what a bad power factor does to energy bills.

4. 4.

   Active Power Factor Correction involves adjusting which waveform?

   Hint

   What waveforms need to align for efficiency?

5. 5.

   Given a system with a power factor of 0.7, calculate the real power consumed if the apparent power is 500 VA.

   Hint

   Use the formula P = S × PF.

6. 6.

   A factory experiences higher electricity costs due to a low power factor. What steps can they take to improve it?

   Hint

   Think about reducing harmonics and improving alignment with the grid.
