3-Phase Voltage Monitors

All SymCom voltage monitors are microcontroller based and are factory calibrated for highly accurate and precise voltage measurements to provide high sensitivity while minimizing nuisance tripping. The high accuracy and precision of these devices allows them to detect a single-phase condition or voltage unbalance even with regenerated voltages present. Uncalibrated devices require low sensitivity to voltage faults to prevent nuisance trips, thus may not trip in the presence of regenerated voltages.

SymCom voltage monitors are built with transformer power supplies which makes them highly resistant to damage caused by small voltage transients on the power system. Other types of power supplies such as switching, resistor limited and capacitor limited, are typically more easily damaged by transients.
