NRPC seeks faster busbar protection at substations

Untitled - 1Dissatisfied 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.
