As reactive-inductive loads and line reactance are responsible for voltage drops, reactive-capacitive currents have the reverse effect on voltage levels and produce voltage-rises in power systems.

Types of Electrical Loads and The Power Type They Consume The reactive component (KVAR) of any electrical distribution system can easily be reduced in order to improve power factor by using capacitors. Capacitors are basically reactive loads. They tend to generate reactive power hence they find good use in power factor correction application.
It’s quite simple. By installing capacitors or capacitor banks. Improving the power factor of an electrical installation consists of giving it the means to “produce” a certain proportion of the reactive energy it consumes itself.
Capacitors are basically reactive loads. They tend to generate reactive power hence they find good use in power factor correction application. So instead of having the utility company supply the reactive power that you will end up paying for, get a capacitor bank and have them supply the reactive energy component as shown below:
A poor power factor caused by a distorted current waveform is corrected by adding harmonic filters. The process of creating the magnetic field required by an inductive load causes a phase difference between the voltage and the current. A capacitor corrects the power factor by providing a leading current to compensate for the lagging current.
The current flowing through capacitors is leading the voltage by 90°. The corresponding current vector is then in opposition to the current vector of inductive loads. This why capacitors are commonly used in the electrical systems, in order to compensate the reactive power absorbed by inductive loads such as motors.
