A Review Paper on Inrush Current Mitigation Technique of Load Transformer for Series Voltage Sag Compensator

Abstract

In many countries, high-tech manufacturers concentrate in industry parks. Survey results suggest that 92% of interruption at industrial facilities is voltage sag related. In recent era boost in computer technology and electronics devices flooded the system with the devices prone to quality of power, as the system consist of electronics load, critical loads, electronics processors which are very sensitive to quality of power. Through survey we found that voltage sag is generally present in power system. Many techniques are available for voltage sag compensation. To maintain the system voltage profile the voltage sag compensator is in need to be installed at various levels in the power system.
