Active Harmonic Filter

We are a well reckoned Manufacturer, Supplier and Exporter of Active Harmonic Filter from Surat, Gujarat. Our Harmonic Filter efficiently cancels out unwanted harmonic currents from an electrical application. Owing to our efficient logistic structure, we ensure that customers all over the world receive their order of Active Harmonic Filter within postulated time.

Highlights :

• Active Harmonic Filters are power-electronic devices that cancel out unwanted harmonic currents from electrical networks by generating harmonic currents in anti-phase with the harmonics to be removed
• Active filters offer varying degrees of selectivity, enabling specific harmonics to be targeted and can be used in Hybrid Harmonic Filters, where they can be used to target higher order harmonics and allow more cost effective Passive Harmonic Filters to remove the lower order harmonics
