The reactive power at the consumer side is merely used for building up a magnetic field, for example, for operating electric motors, pumps, or transformers. Reactive power is generated when power is drawn from the supply network and then fed back into the network with a time delay. This way it oscillates between consumer and generator.

To decrease the voltage drop considerably between the sending and receiving ends by the application of a series capacitor, the load current must have a lagging power factor. As an example, Figure 3a shows a voltage phasor diagram with a leading-load power factor without having series capacitors in the line.
Capacitive reactance opposes the flow of current in a circuit and its value depends on the frequency of the applied voltage and the capacitance rating of the capacitor. The reactance is calculated to determine the impedance of a circuit, which is a measure of the total opposition to the flow of current in the circuit.
