Our Group has been designing and offering Automatic Thyristor Switched multiple Tuned Filter Circuits for the last many years. They are designed to absorb the dominant harmonics from the network, thereby bringing down the THD-I levels to acceptable limits as per IEEE 519 or IEC 61000. Chances of Resonance in the network is eliminated. At the same time, they offer reactive power to the network, thereby improving the power factor of the same.
The other significant advantage is that it eliminates the need for a separate power factor correction system, thereby saving on initial capital cost. It designed for Power Factor Correction and Harmonic Filtration for fast and dynamic loads in industries. It has Dual Power Factor setting suitable for reactive power compensation on Utility supply and DG supply.
The design of these filters is carried out in advanced simulation software taking into account all aspects of the network like fault levels, level of harmonic generating loads, Power factor, individual harmonic components, resonance point etc. Accordingly, the final design is implemented to get desired results.

ACTIVECOMP Thyristor Switching Modules for Tuned Harmonic Filter
The ACTIVECOMP Thyristor Modules is characterized by a high switching speed that ensures the switching on and off of the capacitors in real-time. Thyristor switching modules comprised of solid-state switching elements, which provide reliable, high speed and transient free operation. Thyristor Switching Module have a very high peak inverse voltage (PIV) of 2200V AC; this makes them exceptionally resistant to network Transients. These modules have inbuilt high-speed fans for better cooling with high-temperature protection. With the selection of highly-rated devices and thermal design, the performance of switching modules is way ahead of Switches available in the market.
Harmonic Block Reactors
Harmonic Filter Reactors are the most critical component of Tuned System. In terms of design, operational capabilities and losses, they have many unmatched features. They three-phase reactors are designed with an iron core and air gap. These Reactors are made out of high-quality material. It has been designed with properties like low-temperature rise and lower flux density so that it can operate in worst conditions of ambient and harmonic overloads. They offer a very high degree of linearity and low losses. All the reactors are designed with a single layer strip winding with proper air channels for low-temperature rise.
Capacitor Banks
Super Heavy Cylindrical type Duca Power series Capacitor Banks from M/s Ducati Energia S.P.A., Italy are installed as standard in all Tuned HF Systems. Capacitors are rated voltage of 690V to 1500v for stability and long life of the tuned circuit.
