ORDER
Punjab State Electricity Board
(Board) has filed this petition seeking additional time for fulfilling the
requirements of the State Grid Code (SGC) in respect of Current Transformers (CTs) and Potential Transformers (PTs).
The Commission, in its order of 8.1.2008 directed that the Board may obtain the
recommendations of the State Grid Code Review Committee (SGRC) and submit the same
for its consideration.
2. The
Board in its submissions filed on 7.3.2008 forwarded the recommendations of the
SGRC which are as under:
(i)
Existing CTs and PTs need not be changed
abruptly and new purchases be regulated as per the recommended parameters.
(ii)
To replace in
the year 2008-09, all existing CTs and PTs at the boundaries for inter-state billing and in the
case of all consumers supplied through independent feeders.
(iii)
VA burden of CTs may be reduced from 30 VA as prescribed in the SGC to
25 VA per core.
(iv)
Remaining CTs and PTs at State boundaries
may be replaced in a phased manner by those with new technical parameters only
after unbundling of the Board.
3. In
response to the Commission’s query as to whether its approval was required even
in cases where the proposed parameters exceeded SGC’s
prescription, the Board has clarified that the Commission’s approval in such
cases would not be required.
4. The
Commission has carefully considered the submissions of the petitioner alongwith the recommendations of the SGRC and observes as
under:
(i)
CTs and PTs existing at boundaries for inter-state billing and for
consumers supplied by independent feeders will be replaced with those
conforming to SGC parameters within 6 months of the passing of this order.
(ii)
The cost of replacing
CTs and PTs in the case of
consumers supplied through independent feeders would, however, be borne by the
Board.
(iii)
The question of
replacing CTs and PTs
consequent upon unbundling of the Board would be separately addressed as and
when the contours of the proposed unbundling become known.
(iv)
The Board may within
15 days intimate the schedule for replacing all other CTs
and PTs not referred to above. This aspect will be
separately considered by the Commission.
(v)
On the basis of
the SGRC’s recommendations, the Commission approves
the reduction of VA burden from 30 VA as mentioned in the SGC to 25 VA per core
for CTs.
5. The
petition is disposed of accordingly.
