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.
