Hybrid - Activcomp(PF Control) & Active Harmonic Filtration System

Hybrid Power conditioning system is a combination of Dynamic Activcomp Thyristor based Power Factor Correction System and IGBT fired Active Harmonic Filtration System offers most viable and economical solution for both Power Factor Compensation and Harmonic Mitigation. The designs offered by us are installed for compensation and Harmonic compliance of main transformer or at major load feeders. Though there are standard ratings but any design can be offered as per customer load characteristics and level of harmonic distortion.

Contact our sales office for further details.
