Incoming Power

IUAC is having 11 kV dual HT feeders as incomers from BSES Rajdhani Power Limited. One feeder is coming from Indian Institute of Mass Communication (IIMC) vis ICSSR and the other is coming from Grid-B, 66 kV sub-station in sector B- 5&6 Vasant Kunj. IUAC is having switching facility within our sub-station, between the two feeders in case of failure of any one feeder. The contract demand of IUAC is 1752 kVA and sanctioned load is 1921 kVA.

11kV, HT distribution

IUAC is having a total of 3 sub-stations including two outdoor Compact Sub-Stations (CSS). 11kV power is being distributed to 8 different distribution transformers through HT panels of 3 sub-stations consisting of OCB’s, VCB’s and SF6 circuit breakers, which converts 11 kV to 415 V AC for utilization. The total power of all 8 distribution transformers is 7100 kVA.

LT Power Distribution

LT power from all distribution transformers is being distributed across the campus through LT panels. Few major loads are listed here

• Central AC Plant-1 – having 4x250 TR chillers
• Central AC Plant-2 – having 1x200 TR chillers
• Central AC Plant-3 – having 1x250 TR chillers
• Liquid Helium Plant
• Pelletron Accelerator
• Param Rudra Data Centre
• High Current Injector Facility
• HYbrid Recoil Mass Analyser

Un-interrupted Power Supply Systems (UPS Systems)

IUAC is providing un-interrupted power to all major facilities by using following UPS Systems.

• 3x300 kVA UPS Systems synchronized and load sharing
• 3x200 kVA UPS Systems synchronized and load sharing
• 3x60 kVA UPS Systems synchronized and load sharing
• 3x60 kVA UPS Systems synchronized and load sharing
• 2x500 kVA UPS Systems synchronized and load sharing
