CG range of instrument transformers includes Current Transformers, Inductive Voltage Transformers and Capacitive Voltage Transformers. Our Instrument transformers have significantly contributed to the electricity boards and utilities across the globe. Several thousands of EHV Instrument Transformers have been put into service in various environments in over 60 countries since 1984 and operating satisfactorily.
With the support of our global R & D, we have developed 1200 kV Capacitor Voltage Transformer ( CVT ), which has been successfully type tested.
Our EHV range of instrument transformers uses (Oil Impregnated Paper) OIP as the main insulation system. Napthene based mineral insulating oil (free from inhibitors) is used in the equipment manufactured. This oil is highly stable against oxidation as well as chemical and electrical aging. The capacitor technology used in capacitor voltage transformers and coupling capacitors is all paper or paper plus film (mixed dielectric).
We also offer Medium Voltage Dry Type Instrument Transformers, since 1995. More than 60,000 units of Dry Type Polycrete® Outdoor Instrument Transformers are in operation globally.
Our Instrument Transformer manufacturing units in India also offer Condenser Bushings for power & distribution transformers.
