ABB designed, manufactured, installed and commissioned a 1,200-kV circuit breaker the highest AC voltage level in the world. Once the 1200-kV ultrahigh-voltage switchgear is fully operational, it will have a switching capacity of 10,400 MW - a switch capable of turning ON' or OFF' the electricity generated by 10 large power plants or the combined average annual electrical load of Switzerland and Denmark, within milliseconds. The circuit breaker is deployed at the 1,200 kV national test station constructed by Power Grid Corporation of India Limited (PGCIL), India's central transmission utility, at Bina in the central Indian state of Madhya Pradesh.
