Structural Engineering Research Centre (SERC) of the Council of Scientific and Industrial Research (CSIR) has developed Emergency Retrieval System (ERS) for quick retrieval of power transmission in the event of failure of transmission line towers. CSIR and SERC have signed an agreement for licensing of the ERS technology with Advait Infratech, Ahmedabad.
At present, the ERS systems are imported. There are very few manufacturers across the world and the cost is relatively high. This technological development will enable manufacturing in India for the first time, which will be an import substitute and will cost about 40% of imported systems. ERS has a huge market requirement in India as well as in SAARC and African countries.
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. 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 the failure of transmission lines severely impacts the lives of common people and causes huge monetary loss to the power companies. As the total losses/damages are directly proportional to the outage duration, time is a crucial factor in reinstating or remediating the damaged/fallen structures.
Made of structurally highly stable box sections, ERS is lightweight, modular and reusable. It provides a complete solution from member connections up to the foundation for different types of soil condition. The system is verified through rigorous structural tests. Basic knowledge and tools are enough to assemble and install ERS at the disaster site. Suitable configurations for different voltage-class of transmission line systems are possible. The system is compact and yet provides full functionality on erection. It is designed as a scalable system for 33 to 800 kV class of power lines and can help in building a disaster-resilient society.
