Medium voltage cables, UPS systems, and lighting elements with electronic ballasts  are capacitive  in nature. In businesses where these types of loads are present, shunt reactors are needed to meet the reactive power requirements and keep reactive power ratios within desired limits.

The load profile of businesses changes day by day. Previously, compensation achieved simply  by connecting capacitors  was sufficient. However, the number of capacitive devices in businesses is constantly increasing. Therefore, for proper compensation,  it is necessary to use shunt reactors in addition to capacitors. The size of the shunt reactor  to be used varies depending on the size and load profile of the business   . After a proper analysis of the business, the most suitable shunt reactor should be selected, taking cost into consideration.
