DYNAMIC VAR COMPENSATION
Dynamic VAR compensation uses rapid switching techniques to insert and remove capacitive reactance as demanded by dynamic loads. Many electrical loads have very rapid requirements for reactance that cannot be satisfied with traditional automatic (contactor) switching methods.
These highly dynamic requirements for reactive power can only be satisfied with the most rapid switching techniques that match reactive compensation to load demand. Myron Zucker, Inc. offers a complete range of rapid switching products to provide reactive power compensation, harmonic filtering, and voltage support.
APPLICATIONS
- Designed for rigorous applications, including harmonic-rich environments
BENEFITS OF DYNAMIC VAR COMPENSATION
