Voltage Sag Compensator (VSCOM)

Elimination of Voltage Sags
Instantaneous action
No energy storage required
Simple and reliable design

VSCOM is a non-linear impedance consisting of passive components only - capacitors, reactors, resistors and non-linear resistors. The circuit is designed in such a way that its impedance during normal service condition is very low and is not affecting the network impedance. In case of a phase-phase or phase-ground failure, which is the normal cause of a voltage sag, the impedance of VSCOM will increase and reduce the fault current to a low value thus eliminating the voltage sag.
