been increasing consistently during this period. This has had an adverse impact on
the quality of supply and service to the consumers.
There has also been a marginal decrease in the failure rates of DTs in recent years
especially in the capacities of 250 kVA and above. However, the percentage
failure rate in 25 kVA and 63 kVA transformers still continues to be around 20
per cent, which is certainly high for any distribution system.
It is also ironical that when most of the States are installing capacitor banks at LT
level in order to improve tail end power factor and thereby curb losses, UPPCL
has failed to maintain even the already installed capacitor banks at 33/11 kV level,
leave aside the compensation on LT side.
There has been an inadequacy of the reactive compensation in transmission
system of UPPCL. The situation regarding transformation capacity and available
reactive compensation (at the end of 2003-04) is as under:
Aggregate secondary transformation capacity 12,000 MVA (approx.)
Requirement of reactive compensation 7,200 MVAR
Installed capacity of capacitor banks 4501 MVAR
Capacitors in working order 3,309 MVAR, i.e., about 73 per cent
of the installed capacity.
Such a highly under-compensated system not only leads to low power factor and
low voltage but it also puts additional strain on the system. Details regarding the
position of capacitors is at Annexure-II.
Most of the investment parameters indicate that resources have not been allocated
optimally and the transmission and distribution system has faced immense
neglect. The table below indicates the investments made in the distribution system
during the pre and post-restructuring period. It would be evident that investments
have dried up further after restructuring.
