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

We are engaged in offering high quality Hybrid Harmonic Filter to prestigious buyers. This Harmonic Filter is capable of utilizing the best proprieties from both active and passive filter, resulting in an efficient performance. As a reliable Manufacturer, Supplier and Exporter of from Surat, Gujarat, we assure timely delivery of Hybrid Harmonic Filter all over the world.

Highlights :

• A combination of passive and active technology where the passive section is used to filter low order harmonics, usually fifth and seventh, thus keeping the VAr output minimized, and the active filter is targeted at higher order harmonics only, thereby minimizing the size and cost of the overall solution
• Passive filters generate leading VArs that may be undesirable above a certain level making it more difficult to filter multiple harmonic orders
• Active filters, dependent on their control logic, can use most of their available output to filter out the single largest harmonic on the network
• Fifth harmonic tends to be the most prominent harmonic on distribution networks due to the prolific use of 6-pulse inverter technology, so in an all-active solution, the size of an Active Harmonic Filter may need to be increased to deal not only with the 5th harmonic but with any higher order harmonics that may require filtering also.
