In this paper, the authors will discuss how static Var compensator successfully been applied to control transmission system. The voltage level of the system changes when there is a change in load and the drop in load voltage lead to demand for the reactive power. Static Var compensator is basically a shunt connected Static Var Generator whose output is controlled by adjust the value of capacitive or inductive current. One of the reasons for installing the static Var compensator to improve the voltage profile and increases the system loadability.
