operators/Workers

Combined effort by OMS/FLC/Zonal

team to prevent ED

GPS Mapper Damage Prone Location IdentificationCable Route Tracing

Cable Route Tracing of all the existing 11/33/66 KV Cables. Cable Routes are updated in GIS with the help of GPS Mapper. Approx. 5000 Fault prone locations identified for physical route markers

installation

Implementation

Precise cable route in GIS enhanced the awareness of cable route at root level

Easier to share the cable route profile and position of our UG network to other utilities.

Installation of physical route marker can be done accurately.

GIS Mapping

Introduction of Toll Free Number. 1500 Nos stickers pasted at various

JCB/HDD machines

Around 78 Nos. of Training imparted to JCB/HDD operators

More than 150 Nos call received at Toll Free Number

External Damage mitigation in all such cases with the joint effort of OMS, Zone & FLC Team.

Conventional Route Marker Route Marker with Toll Free Number

Approx. 5000 Fault prone locations identified for physical route markers installation.

3000 Nos Cable route markers installed at various damage prone locations.

Step Ahead RFID ball markers installation on under

ground cable joints. Adding attributes in the RF Marker Date of joints Make of joints Depth Details of jointer

Impact: Efficient and accurate mapping of

assets, better O&M practices, reduced Repair/maintenance costs & prevention of external damage of U/G assets
