Underground power supply system introduced in Rohtak

Chandigarh, Oct 9 (UNI) A major part of the Rohtak town has been benefited by implementation of Rs 18 crore underground power supply system which has enhanced the overall safety level, system reliability and minimised interruptions.

Giving details of the project, a spokesman of the Uttar Haryana Bijli Vitran Nigam said that under this pilot project it was planned to remove the existing overhead 33 KV and 11 KV lines, High Tension and Low Tension lines, distribution transformers and poles etc to ensure power supply in the areas concerned through underground cabling system.

The work has been completed on turn key basis in the identified areas of Old Bus Stand to Mata Darwaja Road, Ashoka Mor to Jhajjar Chungi, Jhajjar Chungi to Jhajjar Mor, Gohana Stand to Ambedkar Chowk, Shant Mai to Sukhpura Chowk and Dayanand Math to Mata Darwaja Road.

The Nigam has removed 3 KM overhead 33 KV lines, 12 KM long 11 KV lines, 110 KM low tension lines and feeding distribution transformers.

To give a modern look the power supply arrangement has been made through fully guarded twenty new Package Sub Stations (PSS) set up on safer points, 1050 feeder pillars including streetlight pillars and 250 streetlight poles. Simultaneously, almost 95 per cent of the existing power supply conventional system has been dismentaled.

Referring to the new arrangement, he said that the PSS is a compact sub station having 11 KV/bus bar with two insulator and intermediate Vaccum Circuit Breaker with over current and earth fault protection to protect the transformer. This is a fully covered compartment having no effect of rain, spark or windstorm. The new system also minimizes voltage fluctuations and helps reduction in line losses estimated upto 20 per cent with an effective ground earthing system.

The consumers get electricity through 'C' type feeder pillars.

One such pillar, on an average, was supplying power to 30 consumers.

About 6 to 7 consumers were being fed from one service cable connected with the pillars. In the event of damage of service cable the electricity supply of a small group of consumers is affected.

The system also minimizes complaints, pilferage of power by hooking the low tension lines and electrical accidents.
