A large number of CG Current Transformers up to 550 kV have been successfully commissioned in more than 60 countries since 1984, operating efficiently in a wide variety of environments.

Models such as Type CT and Type IOSK are live tank types with rated voltages from 72.5 to 800 kV.

These transformers comply with international standards and are certified under ISO 9001:2008, ISO 14001, and ISO 18001 for quality, environmental, and safety management systems respectively.
