The cost of electrical energy is significantly affected by the low Power Factor Penalty (cos ϕ) applied in supply contracts: mainly from this, but also from other important factors, the need to re-phase the systems arises. Power Factor Correction is a technique which, by improving the Power Factor of electric machines, allows the rational use of energy, achieving important economic savings and significant technical improvements.
