Electrical Services Division

Mandate

The primary mandate of ESD is to provide adequate, high quality, reliable and uninterrupted power required for various needs of the research activities and the infrastructural requirements of the centre. To meet this Electrical Services Division designs, construct, operate, maintain and upgrade Electrical transmission and distribution system keeping in mind the system reliability & safety.
The division is also responsible for providing state of the art intercom telecommunication services to the plant site as well as for Energy conservation in the Electrical sphere through auditing and implementing various energy conservation measures.

Expertise

ESD is a centralized facility having expertise in providing uninterrupted power supply by maintaining 33 kV Central Switching Station the nodal Sub-station between two generating stations, Madras Atomic Power Station (MAPS), BHAVINI & Fast Breeder Test Reactor (FBTR) and end users, i.e., all DAE facilities at Kalpakkam. It functions as a nerve centre for electrical distribution network at IGCAR, Kalpakkam. It was commissioned in the year 1977 with single 33 kV Incomer from MAPS to feed off-site power requirements of FBTR and allied labs of the then Reactor Research Centre (RRC).
It has expertise in power transmission systems and distribution systems. All 33 kV equipment like transformers, breakers, isolators, Current & Potential transformers etc are located in an outdoor switch yard. The switch yard is well designed with various protections like underground earth mat, blue metal stones to bring down step & touch potentials, lightning screen, surge diverters etc in line with Indian and International safety standards. The RCC structures carrying all the equipment have been slightly elaborated.
