This project involved implementation of a Dynamic Line Rating system on a 400 kV double circuit transmission line with a total route length of 95 kilometres between Madurai and Tuticorin. The initiative was executed as a digital pilot to support transmission system digitalisation and energy transition objectives outlined in national electricity planning frameworks.

The project included hotline installation of multiple Dynamic Line Rating sensors on live conductors, enabling continuous acquisition of real timeline parameters and local weather data. These parameters are processed through a digital platform to calculate and predict live transmission line loading under dynamically changing weather conditions. The system allows actual line capacity to be assessed based on operating conditions rather than conservative static ratings, thereby improving operational decision making.

The solution enables real time monitoring of conductor temperature, sag and environmental conditions, supporting enhanced situational awareness and more flexible operation of the transmission system.
