Il fattore di potenza nei carichi in alternata in presenza di armoniche non è uguale al cosfi

We'll see why two induction hobs with the same active power can cause very different currents to flow through cables. We'll also discover why the power factor in electronic loads depends not only on the phase shift, but also on the current harmonics. Using a real-world example, we'll calculate the Joule losses in the cables and the energy wasted in a year. Finally, we'll understand why devices designed with Power Factor Correction and compliant with EMC regulations are essential for reducing unnecessary currents and improving system efficiency. ⚡📊 📚 Do you want to learn the basics of electricity easily and without too many technical jargon?
