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.

Oil cooled type of reactors can be made suitable for indoor or outdoor use at all levels of system voltage. Internally the construction consists of a core-less paper-insulated disk winding or layer type winding. 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).

Dry type air core reactors have traditionally been used for current limiting applications due to their inherent linearity of inductance vs. current. For this application, impregnated construction usually become the design of choice because its improves mechanical characteristics enabled the reactors to withstand higher fault currents. Dry type air core reactors are employed over the full range of distribution and transmission voltages, including EHV (high voltage series reactors) and (filter reactors, smoothing reactors) HVDC. This method of construction is extremely robust. Dry type iron core reactors can also be used at low voltage and indoors for applications such as harmonic filtering and power conditioning (di/dt, smoothing etc.).

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.

Usually SVC reactors were imported from Austria for all these years.Now we have manufactured the largest SVC reactor in the country for 60 MVAR SVC system of ABB make.It has been successfully installed and commissioned at a SAIL steel plant since 2 years.

Air cored reactors are manufactured by building the winding on a former with suitable insulations and spacers to hold the winding in strength and to restrain the turns from any movement caused by compressive forces. Reactors are made of Aluminium Copper winding without any core. The reactors can be assembled in vertical as well as horizontal construction.

The Capacitor In-rush Limiting reactors are used in series with capacitor bank to control the in-rush current and to suppress the harmonics. Normally reactors with 0.2% rating are used for in-rush current limiting on neutral side and 6% for line side. Specific ratings between 0.8% to 13% are used for harmonic suppression.

For efficient working of arc furnace, the electrode current should be low and the arc should be longer. To stabilize the arc, the series reactor is installed on primary side of the arc furnace transformer. These are normally in iron cored construction with forced oil and water cooling.

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).
