1. Introduction to shunt reactors. Shunt reactors are used in high voltage systems to compensate for the capacitive generation of long overhead lines or extended cable networks.The reasons for using shunt reactors are mainly two. The first reason is to limit the overvoltages and the second reason is to limit the transfer of reactive power in the network.

Shunt capacitorsprovide reactive power locally, resulting in reduced maximum kVA demand, improved voltage profile, reduced line / feeder losses, and decreased payments for the energy. Maximum benefit can be obtained by installing the shunt capacitors at the load.
Both distribution and transmission systems benefit due to the application of shunt capacitors include: reactive power support, voltage profile improvements, line and transformer loss reductions, release of power system capacity, savings due to increased energy loss.
Usually extra-high voltage (EHV) lines are used to transmit bulk power from remote generations to load centers. These long lines tend to produce significant voltage drops during peak loads. Therefore, shunt capacitors are used at the EHV substationsto provide reactive power. Sometimes these capacitor banks are switched as and when required.
The units can be designed to meet IEC 60871, IEEE 18 and CSA C22.2 standards. A variety of industries can benefit from using high voltage capacitors for increased capacity, stability and power quality, including applications for power generation, transmission and distribution, as well as power consumers in oil and gas and infrastructure.
In industrial and distribution systems, capacitor banks are usually installed at 4.16 kV. Note that voltage ratings may vary from country to country. Let's discuss now the most important locations where shunt capacitor banks are usually being installed. 1. Pole-mounted capacitor banks
Distribution capacitors areinstalled close to the load, on the poles, or at the substations. Although these capacitor units provide reactive power support to local load, they may not help reduce the feeder and transformer losses. Low voltage capacitor units are cheaper than high voltage capacitor banks.
