Power and automation group ABB will develop, design and manufacture a 1,200kV circuit breaker transmission system at Bina in the central Indian state of Madhya Pradesh.

The circuit breaker will be installed at a national test station being constructed by India's central transmission utility, Power Grid Corporation of India (PGCIL).

ABB head of high voltage business Giandomenico Rivetti said this 1,200kV circuit breaker is another example of the company's commitment to remain at the forefront of technology and innovation.

"ABB has pioneered many power technologies in India, and we are proud to build on this heritage by supporting PGCIL for this benchmark project."

The circuit breaker is designed to be housed along with the disconnector in a tank filled with insulating gas and will result in a space saving of up to 60% compared with conventional designs.

Other design features include modular ring type current transformers, partial discharge sensors and composite bushings.

The company said the 1,200kV Bina station will carry out field tests as part of the project's initiative.
