Filter reactors are used along with capacitor banks to form the tuned harmonic filter circuit for a particular harmonic. If different harmonic currents are to be eliminated from the system, number of filter circuits tuned to each harmonic frequency need be installed. Installing filter circuits is necessary where the harmonic exceed the permissible level, otherwise the excessive harmonic currents can cause higher losses resulting in higher temperature and dielectric stresses. Installing filter circuits is necessary where the harmonic exceed the permissible level, otherwise the excessive harmonic currents can cause higher losses resulting in higher temperature and dielectric stresses. We are able to offer Harmonic Filter reactors in oil cooled as well as air cooled version depending upon the customer's requirement.

Series Reactors are connected in series with transmission distribution line or feeder to limit the fault current. Series reactors are also used for load balancing, limiting inrush current in capacitor banks, filtration of harmonics along with capacitors. Other applications include arc furnace installations, load flow control, smoothing of wave form in DC systems. Neutral grounding is also one of the applications of series reactor.

To prevent the stray flux from passing into the steel enclosure two different methods of construction are employed in oil cooled reactors. The first consists of laminated core-plate about the winding to contain the flux (Magnetic shielding) and the second prevents the flux from entering the enclosure by providing a non-magnetic screen of aluminium surrounding the winding (Non-Magnetic shielding).
