Dissatisfied with the progress
of implementing busbar
protection at 220kV and
400kV substations, the Northern
Regional Power Committee has
decided to take up the issue in the
upcoming meeting of the committee.
NRPC had earlier asked the northern
region power utilities to submit an
action plan for implementing busbar
protection at substations.
Further to this, a consolidated
proposal was decided to be put up
with Power Systems Development
Fund managing committee.
However, despite the committee's
efforts, not much progress has been
made in implementation the
protection system at the sub
stations as about 50 per cent
substations in the region still do not
have busbar protection.
In the follow-up meetings after
the committee's decision to install
busbar protection, difficulties
were pointed out in retrofitting
bus bar protection at 220kV
were being encountered as the
original vendors have to be called in
to implement it.
As no such problem in the
retrofitting at 400kV sub stations is
being faced, the committee decided
that bus bar fittings in the 400kV sub
stations would be given priority and
all new 220 kV sub stations would
come up with busbar protection. The
protection at old 220kV substations
would be implemented in a phased
manner. The utilities have been
asked to indicate a timeframe for
completing the installation of busbar
at their substations in the upcoming
meeting. In the meeting, the progress
of northern region utilities will be
reviewed. Also, methods to expedite
the provision of busbar protection
will be deliberated further.
