Power Grid Corporation of India, the Central transmission utility, has planned to have all its substations unmanned by 2013. R.N. Nayak, CMD, PGCIL, said this at a recent event in New Delhi. Explaining the concept, Nayak said that there would be cameras observing the functioning of all devices and equipment, and the substation will be virtually managed by National Transmission Asset Management Centre at Manesar, Haryana.

Nayak assured all help to the industry for indigenous manufacture of new products and technology; and advised the industry to manufacture line arresters and MOV devices domestically in the coming years. Nayak further said "Line arresters are the future. We are ready to give our full support to the industry, but they should focus on manufacturing line arresters as these are urgently needed in the transmission lines in north Bengal, evacuating power from the north eastern states.''

Appreciating the manufacturers for developing the 1,200kV system in India, Nayak said India needs more technologies to be indigenously manufactured. These kinds of technical conferences are beneficial for the manufacturers as well as the user utilities. Nayak urged IEEMA to continue organizing such international technical conferences in the future as well.

Protection device: Surge arrester is one of the most critical equipment for safe and reliable operation of electrical power system. Surge arrester plays an important role in limiting switching and lightning surges on main equipments like transformers, reactors and circuit breakers, etc., by diverting these surges to ground. The Indian surge arrester industry has come of age and has been able to design, test and supply surge arresters up to 1,200kV operating level.
