    In our daily routine life majority of electric loads  usedare inductive in nature. Adequate supply of active power and reactive power must be supplied to these loads to ensure proper operation. If not provided with required active power and reactive power, these inductive loads burdens the system unnecessarily. Hence resulting in low power factor.In a local electrical distribution system it in uneconomical to upgrade existing network for improvement of power factor.In weak grid system residential consumers use voltage stabilizers to cope up with poor quality of voltage, while industrial consumers use switched capacitors. But voltage stabilizers regulate the voltage on cost of drawing more current from system. On the other hand switched capacitors technology is not robust enough to handle instant variations in power demand. Low power factor on local grid systems can be addressed using static var compensators. In this paper designing of SVC for local grid system is discussed.
