Introduction to Power Factor Correction PFC Capacitors and …
For an ideal electrical load, the power factor is equal to 1.0 (unity power factor). This means that all the power drawn by a load is used to do useful work. However, it is difficult for an actual electrical load to achieve that. The impedance for the load represented by Figure 5 is given by Equation 3, where XL is the inductive reactance and …

Using capacitors to regulate the voltage in electrical networks
Capacitors are made within a given tolerance. The IEEE standard allows reactive power to range between 100% and 110% when applied at rated sinusoidal voltage and frequency (at 25 C case and internal temperature) (IEEE Std. 18-2002). In practice, most units are from +0.5% to +4.0%, and a given batch is normally very uniform. ...
