It is very important to ensure that electricity is correctly used. Every piece of equipment must be designed to ensure maximum global efficiency in transforming the source of energy into work. Among the measures that enable electricity use to be optimized, improving the power factor of electrical systems is the most important. Utility companies offer incentive to consumers in form of discount on KWH charges or less unit rates if billing is done in KVAH instead of KWH.
It is a known fact the electricity users relying on alternating current – with the exception of heating elements – absorb from the network not only the active energy they convert into mechanical work, light, heat, etc, but also an inductive reactive energy whose main function is to activate the magnetic fields necessary for the functioning of electric machines.
The power factor is thus the ratio between active power and apparent power (vectorial sum of active and reactive power), an indicator of the quality of facility’s electric system since the lower the power factor is, the higher the inductive reactive component will be in relation to the active component.
It is possible to produce reactive energy, where necessary, by installing power capacitors or automatic power factor correction systems. Capacitors absorb a current that is 180º out of phase with the inductive reactive current; the two currents are algebraically summed together so that circulating upstream from the point of installation of the capacitor is a reactive current that is equal to the difference between the inductive and capacitive currents. The exchange occurs between the capacitor and user; this is why we say that they capacitor supplies reactive energy to the user. These come equipped with following outstanding features
