‘RED LIGHT’ will tell where the power has gone off

English translation of newspaper article in Hindi Newspaper ‘Dainik Bhaskar’ of Bhopal, Madhya Pradesh, India

English translation of newspaper article in Hindi Newspaper ‘Dainik Bhaskar’ of Bhopal, Madhya Pradesh, IndiaFault rectification time will reduce by 50% by installation of new devices.

Manoj Joshi, Bhopal

Linemen now will not have to wander to look for faults. Electricity company is soon going to buy overhead fault indicators. When this device is installed on line, red light indication will show the direction of fault. In the first phase, these devices will be installed in Govindpura and Mandideep industrial areas.

Officials of the electricity company believe that more time is wasted in fault location than in fault rectification. To get rid of this persistent problem, the electricity company will install overhead fault indicators on 11 KV lines.

How does fault indicator work?

The device is mounted on each section. Each section is mounted with three fault indicators. In the direction of the fault, corresponding fault indicator glows with red light. The field crew can straight away go to the last glowing fault indicator and start their work.

This is being used in Delhi and Haryana

According to officials, a Tata Group Company, North Delhi Power Limited, have installed these devices on a pilot project

Haryana Electricity Company has also installed fault indicators on few lines.

Proposal was received at ELECRAMA

Some time back few officials of the electricity company had visited the exhibition of electrical equipments ‘ELECRAMA-2008’. There, representatives of an American company , E O Schweitzer, had suggested this proposal.

OFI will be installed at Govindpura and Mandideep

In the first phase, OFI will be installed in the three feeders of Govindpura industrial area and Durga Steel feeder of Mandideep. 200 devices will be procured for this purpose. One device costs around INR 9600. In the next phase, OFI will be installed on more fault-prone lines.

  • OFI will be installed on Govindpur and Mandideep Lines
  • One ‘OFI’ costs around INR 9500
  • 200 devices will be procured which will be installed on more fault-prone areas

“The screening committee of the distribution company has approved procurement of fault indicators. With this lot of time of the field crew will be saved” – S A Ansari, Superintending Engineer (IT & Computer Cell), Electricity Distribution Company
