Metal-enclosed harmonic filter bank systems are hybrid solutions used at medium and high voltage levels for both reactive power compensation and suppression of harmonic distortion.

They combine capacitors with series-connected harmonic filter reactors, disconnectors, circuit breakers, a power factor controller, analysers and monitoring systems in a compact, safe and site-ready design.
 

Developed with Enersolix engineering, these systems deliver harmonic suppression compliant with IEEE 519 and IEC 61000-4-7 on MV sites, together with high-quality compensation.
