ABB energizes transformer at world record voltage level of 1.2 million volts

07 Oct 2016 Evaluate

ABB has developed, manufactured and energized a 1.200-kilovolt (kV) ultrahigh voltage power transformer to support India’s plans to build a 1,200 kV transmission system, supplementing the existing 400 kV and 800 kV transmission grids as demand for electricity increases. This 1.2 million volt transformer represents the highest alternating current voltage level in the world and is installed at the national test station at Bina, Madhya Pradesh in Central India, as part of a collaborative initiative by the country’s central transmission utility, Power Grid Corporation of India (Power Grid). The transformer was manufactured and tested at ABB’s facility in Vadodara.

India’s geographic span means that resource-rich generation centers and urban and industrial load centers are often far apart calling for efficient power transmission. Along with the country’s commitment to enhance the contribution of renewables, these factors are driving the development of an ultrahigh voltage transmission infrastructure.  The 1,200 kV transmission system will help strengthen the grid and enhance load capacity up to 6,000 megawatts (MW). Transmission at higher voltages enables larger amounts of electricity to be transported across longer distances, while minimizing losses. At the same time, less space is needed for fewer transmission lines which reduces the environmental impact and overall cost.

ABB is a leading global technology company in power and automation that enables utility, industry, and transport & infrastructure customers to improve their performance, while lowering environmental impact. ABB Group of companies operates in roughly 100 countries and employs about 135,000 people.
