A reactor or a capacitor stores the reactive power generated by the ac power source during a quarter of a cycle and returns the same power to the source in the next quarter cycle. In other words, the reactive power oscillates between the source and the reactor or capacitor at a frequency equal to twice the rated value. However in nature, most of the loads …

Shunt compensation with capacitor banks reduces kVA loading of lines, transformers, and generators, which means with compensation they can be used for delivering more power without overloading the equipment. Reactive power compensation in a power system is of two types—shunt and series. Shunt compensation can be installed near the load, …
With a reactive power compensation system with power capacitors directly connected to the low voltage network and close to the power consumer, transmission facilities can be relieved as the reactive power is no longer supplied from the network but provided by the capacitors (Figure 2).

In some cases, special circuits are used to measure the reactive power. For example, the reactive power measurement can be performed with compensation capacitors to determine the amount of reactive power compensation. Here, capacitors are added or removed to minimize the phase shift angle and thus compensate for the reactive power.
