WORKS DESIGN BASIS FOR ELECTRICAL WORKS FOR TWD VFD PUMPS
This document defines the minimum basis of design for design, supply, installation,
testing and commissioning of the TWD pumps to VFD and higher capacity.

Codes and Standards & statutory requirements with latest revisions and amendments, in
a) Bureau of Indian Codes and Standards
b) Indian Electricity Act,
c) The Indian Electricity Rules,

4. POWER SOURCE DETAILS
HT power at 11 KV is presently available from NPCTSL. However, since TWD pumps
are being augmented, the requirement of new power distribution is unavoidable and has
to be implemented to handle the increase in load. The existing MD is 260 Kva sanctioned
by NPCTSL and this may have to be increased to 275 Kva since we have already touched
218.5 Kva in one of the previous months.
4.2 HT Breaker: Available and transformer capacity and DG capacity need not be increased
from the present ratings.
5. POWER SUPPLY DISTRIBUTION SYSTEM
5.1 Voltage and frequency variation
Voltage : 415V +5 %
DESIGN BASIS FOR WORKS:
The existing two HSD pumps are being augmented to 55 Kw and hence considering that
the existing DG shall be used without upgrading it has been suggested to use VFDs since
starting currents would be low and PLC integration if required for the future would be
available on call.
