• Every element in the system, in or from which, energy is measured would have a
Distinct Identification Number (DIN). From this number alone, it would be
possible to link it to details of its electrical connection (e.g., from the DTC’s
DIN, one will know the 11 kV feeder, 33/11 kV sub-station, 33 kV feeder in
EHV S/S, EHV transformer feeding energy, etc., to which it is connected) as
well as the administrative linkage (such as geographic location, controlling
section/ subdivision/division/circle/zone, etc., each of these also having their
unique identification numbers). Computation for any compilation of data will be
done from this primary information of meter readings recorded in the system.
• Apart from output for the energy loss in the elements as obtained from the data
so collected, further information to find out elements where actual loss exceeds
normative loss (e.g., < 1 per cent in EHV transformer or near zero for sum of
energy received on a 33 kV or 11 kV busbar and flowing out of it, etc.) or
difference in energy sent and received in respect of an express feeder (calculated
on the basis of length of the feeder, peak load, loss load factor, etc.) to enable
rectifying relevant energy meter(s) or check correctness/tampering of input
quantities should be prepared for the concerned staff to take time bound
corrective action.
• Proper investigation in respect of express feeders where energy received is more
than energy sent is required to be done as this does not automatically suggest that
no action is necessary in case of such feeders. Such a situation could arise
because of incorrect/tampering of input quantities (e.g., loss of PT supply, large
difference in voltages at the PT terminals and energy meter terminals, incorrect
CT ratios, etc.).
From the above information, the energy lost in individual element/location will be
presented in kWh lost and not in per cent of loss. The targets for reduction of the loss
will be set separately for each individual officer-in-charge of the element in terms of
reduction of kWh lost and reduction in money lost by applying the relevant rate per
unit of energy (e.g., industrial rate per kWh lost in MIDC area or in respect of an
express feeder for industry). This final result that will be monitored by higher officers
at various levels when Energy Audit is done in the manual mode as per the procedure
suggested above in the intervening period.
In future, when computerised Energy Audit module is commissioned, there will be no
need to send any information to any office as the same would be based on the primary
information maintained in Energy Audit module of the Computerised Information
