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

ABB has developed, manufactured and energised 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 grid 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 Limited (POWERGRID). The transformer was manufactured and tested at ABB´s facility in Vadodara.
