It's 1200 kV. That's right 1200. Most of the power transformers that are in a substation near you range from 138kV-230kV. Going to be put in Indian country. :) As in the country.
This thing cost $330M
Vijai Electricals' chairman and managing director, Jai Ramesh, handed over the 33MVA, 1200KV class, ultra high voltage power transformer to S K Chaturvedi, chairman and managing director of Power Grid Corporation of India Limited.
To support the government's plan for augmentation of installed power generation capacity and corresponding transmission corridors, the country would, in the near future, need 1200 KV AC as next transmission voltage for bulk transfer of power of the order of 3,000 to 6,000 MW per line from power generation complexes in east and north east to load centres located in northern and western regions, the company said.
1200 KV AC would be the highest transmission voltage in the world and to develop this cutting edge technology indigenously, Power Grid Corporation of India took the lead to establish a 1200 KV test station at Bina in Madhya Pradesh with experimental line of 1.6 km. The transformer developed by Vijai Electricals would be installed at the substation
