At Transmitting centre, two Nos. of 11 KV feeders are terminated at 6-pole structure in A.I.R. campus along with metering facility, from Chhattisgarh State Electricity board. Under 10th Plant and replacement of 100 KW MW X’TR following works were carried out :
1. Two length of H.T. cable from 6 pole structure to H.T. switch Gear room replaced.
2. Old 02 Nos H.T. O.C.Bs replaced by new 4 panel H.T. VCB.
3. 02 Nos. 11 KV / 450 volts H.T. Transformer have been replaced by new one.
4. Earlier, there were no A/B switches at 6 pole structure. For maintenance purpose, 02 Nos. A/B switches are installed.
5. L.T. switchgear panel has been replaced by new one with provision of essential and non-essential light and power load. The Output of 125 KVA D/G set is also terminated on this panel.
6. All the old Kit Kat type I/C switches in distribution panel were replaced by MCB for Light and power of old building.
7. The electrical light and power wiring along with switch and socket has been replaced by new one in old building.
8. Twin light decorative tube rod fittings have been replaced by mirror optic twin light tube rod fittings in X’TR Hall and Emergency studio.

The old D/G set 62.5 KVA, Make – Ruston Sl. No. 48G1178 has been taken out of the circuit in Feb. 2007 and diverted to AIR Ambikapur & new D/G set 125 KVA provided by M/s. Jeevan Diesels electrical Division, Silvasa has been installed in Feb. 2007. During the year HT cable of MPSRTC feeder became defective, hence it was replaced with the new one, now both the feeders are working satisfactorily. The HT feeder line namely MPSRTC feeder cable was damaged and it was repaired twice but it could not work for long time. Insulation was found poor, hence the same was replaced with a new 11 KV HT cable.


There were two independent 400 V feeders for Studio-cum-office complex earlier. The voltage on one of the feeder (locally called LIC feeder) remained always low. Due to this, A/C Plants were unable to be put on this particular feeder. This problem was discussed with officials of C.S.EB. They suggested to obtain the H.T. connection in lieu of existing LT ones as in the mean time, 1 KW FM X’TR, 10 KW IGNOU X’TR, CES etc. also came into existence . Hence, H.T. connection of 11 KV with contract Demand 178 KVA was energized on 19.08.2006. In year 1998, CE (WZ) under MR Scheme supplied a new 25 KVA D/G set. It was installed and brought in operation on 22.04.1998. The old 22.5 KVA D/G set was auctioned in 2003. Another new DG set of 62.5 KVA , Kirloskar make is provided for 10 KW FM transmitter. The old power supply cables of studio and office complex were replaced by new ones in March 2009, and LT panels 02 nos. of switch gear room were replaced by new panel in March 2010.
