Council of Scientific and Industrial Research (CSIR), constituent laboratory Structural Engineering Research Centre (SERC) based in Chennai, has developed an indigenous technology, Emergency Retrieval System (ERS), for quick retrieval of power transmission in the event of failure of transmission line towers.
At present, the ERS systems are imported and the cost is relatively high. This technological development will enable the manufacturing in India for the first time, which will be an import substitute and will cost about 40% of imported systems.
ERS is a lightweight modular system that is used as a temporary support structure to restore power immediately after the collapse of transmission line towers during natural calamities such as cyclone/earthquake, or manmade disruptions.
Made of structurally highly stable box sections, ERS is lightweight, modular and reusable.
ERS can be assembled quickly at the disaster site for restoration of power in 2-3 days, whereas the permanent restoration may take several weeks.
This development is very significant as failure of transmission lines severely impact lives of common people and causes huge monetary loss to the power companies.
