One of the most ambitious plans of India in the power sector, is the development of 1200 kV Ultra High Voltage ( UHV ) power transmission system, envisaged by Power Grid Corporation of India ( PGCIL ) to cater the increasing need of bulk power transmission over long distances across India. Although some decades ago few UHV pilot projects have been tried out by USA, Italy and Russia, this is the first time India is planning for a 1200 kV UHV Transmission systems which soon will be a reality in India. The Indian plan is to establish a 1200 kV test station at Bina in MadyaPradesh ( Central India ) by Dec 2009, where these products will be put in service for investigations and study purposes and by 2013 establish commercial transmission systems.
In view of this, Crompton Greaves Limited ( CGL ) has successfully developed their first 1200 kV product. This completely indigenous development of 1200 kV Capacitive Voltage Transformer ( CVT) is successfully completed on Jan 1st, 2009. The CVT was successfully tested both at CGL’s Extra High Voltage laboratory at Nasik and also at Central Power Research Laboratory ( CPRI) at Hyderabad.
