Reactive Power Compensation Systems
Two decades of experience in the engineering and supply of the Reactive Power Compensation
systems gives ISG, a leading edge in this field. ISG has the capability to undertake the
harmonic and reactive power measurements at site upto 33kV and offer total solutions on
turnkey basis in supplying the Power Factor Improvement and Harmonic Suppression.
The application of this system is to
improve the Quality of Power available to the industry by reducing the voltage variations,
improving the power factor, reducing the voltage flicker and improving the transient
stability of the power system.
ISG has supplied Harmonic Suppression Filter banks and Power Factor improvement Capacitor
banks upto 100 MVAr, 33 kV to metal industry applications, viz., Furnaces & Rolling
Mills.
The scope and supply in the range include Thyristor Valves and cooling system, Thyristor
Controlled Reactors, Capacitor banks, Tuned Filter Banks, Digital microprocessor control
system and associated H.T. and L.T. Switchgear.
