Power Transformers

Power Transformers

Power Transformers Units manufactures a wide range of Power and Distribution Transformers as well as Reactors ranging from 160kVA to 1500 MVA12kV ~1200kV Class, conforming to IEC, ANSI, IS, BS and other International Standards. CGPISL manufactures wide variety of Transformers like Generator Transformers, Distribution Transformers, Solar Transformers, Green Transformers, Unit Auxiliary Transformers, Shunt Reactors, Furnace Transformers, Locomotive and Track side Transformers.

CGPISL is a preferred supplier for a wide range of Transformers and Reactors for many critical applications. CGPISL is the first Indian manufacturer to develop and supply coupling transformers for dynamic reactive power compensation (DRPC) applications like static synchronous compensator (STATCOM), Static VAR Compensator (SVC) etc & also the first manufacturer of 132KV Green Transformers in INDIA. CGPISL has two Plants to manufacture Transformers one located at Bhopal for Power Transformers and other located at Gwalior for Distribution Transformers, Madhya Pradesh, India. Manufacturing Units are accredited with certifications like ISO 9001, ISO 14001, ISO 18001, Integrated Management OSHAS 18001 and DSIR approved.

Generator Transformers

Generator Transformers

Generator Step-up Transformer units are used to increase the voltage of a generator and connect the supply to a bus bar. Generator Transformers are also used to limit the fault level of the generator in case of a fault. Transformers used for these applications are called Generator Step-up Units. These Transformers are designed to operate at near full load.

Generator step-up transformers are manufactured by CG in accordance to the latest applicable national and international standards. Our transformers meet the needs of utility, industrial and commercial customers. Typical generator step-up transformers have cover-mounted primary and secondary bushings. However other configurations can be provided. Every time a fault occurs in the grid, these transformers are subjected to stress. As these transformers are connected to the grid, they are subjected to constant voltage fluctuations. Voltage fluctuations cause stress to the transformer windings. These windings have to be specially designed to withstand these stresses. Localized heating is another issue which is a result of over excitation by the generator during voltage fluctuations. Localized heating can damage the metallic accessories of the transformer. Generator step-up transformers manufactured by CG India have effective low temperature rise.

A distribution transformer is the type of transformer that performs the last voltage transformation in a distribution grid. It converts the voltage used in the transmission lines to one suitable for household and commercial use, typically down to 240 volts.

  • Automated production resulting in uniform quality by using CNC machines.
  • No axial force under short circuit condition due to foil construction resulting in increased reliability.
  • Increased withstand capacity during short circuit due to increase in the surface area of winding.
  • Compact Transformer.
