Tata Power-DDL becomes first utility in India to implement GPS mapping technology and active RFID markers

  • Technology helped reduce the effective time to locate the cable fault to half (from an average of 90 min to 45 min)
  • Mapping of 1200 cable route and installation of 1,000 RFID markers completed in the first phase
  • Technology to be expanded in the remaining cable routes in a phased manner

New Delhi: Tata Power Delhi Distribution (Tata Power-DDL), the pioneer in power distribution in India, has always been at the forefront to provide world class services to its consumers through the adoption of innovative solutions and latest technological interventions. Keeping in view of the same, the company has implemented GPS mapping technology to map its underground cables along with RFID (Radio-frequency Identification Detector) marker installation on cable splices for speedier fault location and resolution. Tata Power-DDL is the first utility in the country to implement the above technologies.

Technology revolution in power distribution – Implementation of GPS mapping and active RFID markers

  • Reduction in effective time to locate cable fault by half (from an average of 90 min to 45 min)
  • Easy and faster identification and fetching of details of underground power cable network route at any location
  • Speedier resolution in case any fault develops in the underground cables
  •  Mapping of approx. 1,200 cable routes and installation of 1,000 RFID markers in the first phase completed. To be expanded in the entire remaining cable routes in a phased manner

Tata Power-DDL has presently carried out mapping of approximately 1,200 cable routes and installation of 1,000 RFID markers in the first phase and is planning to expand it to the entire remaining cable routes in a phased manner. Tata Power-DDL, with predominant urban geography, has a vast underground network, to the tune of 3,100 circuit km of 66KV, 33KV and 11KV underground cables, which delivers reliable and quality power supply to its valuable customer base. Any untimely failure of this critical power delivery asset results in customer dissatisfaction and loss of revenue due to unserved energy and expenditure incurred on repair and replacement.

The technology is aimed to identify the route of underground power cable network at any desired location as well as to fetch the details of any joints through RFID detectors over and above the ground level. It will help to provide speedier resolutions in case any fault develops in the underground cables.

GPS mapping technology works by collecting location data tags of the routes and mapping it with the accurate location received from satellites. The data is further incorporated with existing Geographical Information System (GIS) network of TATA Power-DDL. The company is tagging its cable routes via the technology to create an accurate mapping of the cable routes along with the RFID markers on joints not only for faster restoration in case of cable faults but also for fetching pre-fed details from the splices (details in terms of depth of joint, make of joint, date of installation etc.). Any fault in underground cable and the route of the cable can then be easily traced using the fault locator and RFID detectors.

Speaking on the initiative, Praveer Sinha, CEO and MD, Tata Power-DDL said, “At Tata Power-DDL, we continuously innovate and strive to introduce new technological initiatives to provide world class services to our consumers. I am sure, the GPS mapping technology in along with RFID marker installation on splices will not only ensure to trace accurate cable route and its fault location but will also help in speedier resolution to any issues related to underground power cables to improve upon reliability. Since the implementation of the technology, Tata Power-DDL has managed to locate and fix major and minor underground cable faults (around 1,000 nos. of 66KV, 33KV and 11KV cable faults per annum) in an accurate and speedier way resulting in less downtime in its area of operation. We have reduced the effective time to locate the cable fault from average 90min to 45min after applying this technology.”

Tata Power-DDL is also coming up with some more innovative product, process and technology in near future to ensure complete remedial action against some other vital issues like external damages of cables which results in untimely and unwanted interruption at times.
