The paper presents voltage restoration system is class of custom power device providing consistent distribution of power quality. It use series connected custom power apparatus which is aimed to defend sensitive loads from supply side distribution except for outage. Mainly we used UPS stabilizer to reduce voltage and the stabilizer will operate when the voltage is increased. So we designed dynamic voltage restorer that operates both condition like increase and decrease of voltage. So this is advantage and more accurate and also it is less costly then UPS and stabilizer. Due to installation of this system battery life can also be increased because when variation occurs in voltage supply from line will be continued from line and difference of voltage will be taken from battery. For example in UPS if input voltage is 180v, circuit will be trapped and entire load will be on battery that generate 50v AC inject to it with in phase, same way if output is 260v and generate 30v AC and inject it with out of phase signal in this way the output will be fixed at 230v AC this is advantageous and battery life will also increase.
