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.
Two shunt reactors, each rated by 60 Mvar and 15 capacitor banks with an overall power capability amounting to 150 Mvar, were installed there in 2009.

An inductor, also called a coil or reactor, is a passive two-terminal electrical component which resists changes in electric current passing through it. It consists of a conductor such as a wire, usually wound into a coil. Energy is stored in a magnetic field in the coil as long as current flows. When the current flowing through an inductor changes, the time-varying magnetic field induces …
