How can power factor be corrected
WebThus, our example circuit started out with a power factor of 0.705 lagging and was corrected to a power factor of 0.999 lagging. Review The poor power factor in an AC circuit may be “corrected”, or re-established at a value close to 1, by adding a parallel reactance opposite the effect of the load’s reactance. Web22 de mai. de 2024 · Figure 9.4.1: Circuit for Example 9.4.1. First, the power factor is the cosine of the impedance angle. At 60 Hz, the reactance of the 100 mH inductor is − j37.7Ω. This is in series with the resistance for a load impedance of 100 − j37.7Ω or 106.9∠20.66 ∘ per leg. The cosine of this angle is 0.9357.
