IEEE 519 – Active Harmonics Filters

HARMONIC CONTROL IN ELECTRIC POWER SYSTEMS

Guaranteeing Safe Operation Improving Energy Efficiency

Sinexcel Active Harmonic Filter can realize 2nd to 50th harmonic compensation, compensation ratio can be set selectively by the customers, output compensation current follows the system harmonic variation, devoted to green power quality.

Different loads generate variety harmonic content which changes dynamically during different working conditions.
