Concept Note regarding External Electrification work of addition and alteration in theInstitute building.

Work of external electrification of building has been divided into two parts.

Part one of the external electrification has to be carried out before demolition of annexe building.Equipment required for part one has been designed in such a way that it would be used in finalstage of part two also.

Work of part two pertains to final shifting of the equipment to the basement of new Annexe Building.

Part one pertains to shifting of equipment from the basement and to maintain the continuity ofelectric supply to the main building till completion of new annexe building. This part one mainlyconstitutes of following activities

1.Fabrication and supply of main LT Panel and installing the same at ground floor near thetransformers.

2. Dismantle and shifting of DG’s AMF Panel from the basement of annexe to ground floor nearmain LT Panel.

3. Connection of newly installed AMF Panel to DG and main LT Panel.

4. Connection of main building distribution boards (cables) to the main LT Panel.

5. Energisation of main LT Panel from DG set.

6. Steps 1 to 5 above will result in restoration of electric supply to the main building from DG set .

7. Getting the BSES Yamuna Power limited main HT metering panel shifted temporarily from thebasement of annexe to suitable place near transformers at ground floor. This work will be carried outby BSES. CA institutes to write a letter in advance to BSES in this regard. Follow up work will be putin the scope of external electrical contractor. Official charges for this work will be paid by the CAInstt.

8.Supply and installation of 11 KV 3 Panel Vacumn Circuit Breaker (VCB) panel at ground floor .

9. Dismantling of HT and LT terminations of two numbers existing transformers.

10. Connection of BSES metering panel to VCB panel and from VCB Panel to transformers.

11. Connection of LT terminals of transformers to the main LT Panel.

12. Energization of transformers from BSES supply..

-31-

13. Steps No.7 to 12 will result in restoring BSES supply to the main building and DG set will be puton emergency.

Once activities from Serial No. 1 to 13 of Part -1 are completed demolition of annexe building canstart.

Part 2 of external electrical work will start once the annexe building is completed .Various activitiesfor this Part-2 are as under .

a. Main LT panel will be disconnected from BSES transformer supply and put on DG supply tomaintain electricity to the main building during the transit period.

b. BSES will be asked to shift the metering panel from ground floor to its new permanentlocation in basement of annexe.

c. Dismantling of HT VCB 3 panel board and shifting the same to the basement of Annexe.

d. Two number new dry type transformers of 500 KVA each will be procured and installed inbasement.

e. HT cable connection from metering panel to 11KV VCB Panel and from 11KV VCB panel totransformers will be made.

f. New LT cables to be laid from position of main LT Panel in basement to distribution boardsin main building.

g. Dismantling of main LT Panel from ground floor and shifting the same to the basement.

h. Dismantling of DG’s AMF Panel and shifting the same to basement.

i. Connection from LT side of transformer and AMF panel to the main LT panel.

j. Energisation of supply from BSES to the transformers.

Steps a to j mentioned above will results in completion of electrical supply to the main and annexebuilding.

Tender for external electrical work will be made in two parts. Part 1will be executed at present andPart 2 will be completed after completion of annexe building. Every effort will be made to maincontinuity of supply to the main building during the transit period.

-32-

Present electrical equipment installed in the basement of annexe is very old and obsolete exceptAMF panel. As such all equipment except AMF panel will be discarded. Since oil type equipmentcan not be installed in basement there-fore new dry type transformers will be installed.

In order to accommodate the shifting of equipment from basement to the side of transformers acovered shed will have to be put in place by removing the cooling towers which are redendent.Details of shed will be given as soon as new equipment details are available.
