Crompton Greaves dispatches 1200 kV autotransformer to PowerGrid

07 Dec 2011 Evaluate

Crompton Greaves, power equipment and electrical appliances maker, has dispatched the first indigenously designed 1,200 kV autotransformer to Power Grid Corporation (PGCIL). The company built this transformer as a research and development programme by Crompton Greaves and has tested the same in October at Crompton Greaves' transformer division in Mandideep, Madhya Pradesh.

PGCIL collaborated with manufacturers and Crompton Greaves was selected as one of the major partners to develop the equipment.  The 1,200 kV AC will be the highest transmission voltage (UHV) in the world. To develop this frontier technology indigenously, Power Grid took the lead to establish a 1,200 kV test station at Bina (Madhya Pradesh).

Globally, the 1200 kV UHVAC (ultra-high voltage alternative current) is limited to a few countries such as Russia (1,200 kV), Japan (1,100 kV), Italy (1,050 kV) and China (1,100 kV).
