Three Phase Passive harmonic filters from EMIS are designed and manufactured to provide an economical and sturdy solution for harmonic mitigation in power systems. These filters effectively maintain THID 5% in compliance with current and voltage requirements of
IEEE 519. Passive harmonic filters being a harmonic absorption type, absorbs the harmonics from both downstream as well as upstream within its range. Thus they prevent the current harmonic from circulating and getting absorbed within the equipment and also stop it from flowing back to the upstream power grid.
