Dynamic VAR Compensation – Dyna-VAR™

A reactive power compensation system designed to stabilize voltage and reduce equipment shutdown risks.

Dynamic Reactive Power Control for Voltage Stability

The Dyna-VAR system is based on proven medium voltage PWM converter technology and provides dynamic control of reactive power—both leading and lagging. It improves voltage stability across the facility, minimizes voltage dips, and reduces the risk of equipment trips and shutdowns due to transients.

Based on proven drive converter technology
Dynamic control of leading and lagging reactive power
Minimizes voltage dips due to high lagging VAR loads
Stable voltage minimizes risk of equipment shutdowns
