Emergency Retrieval System (ERS) for Power Lines

Natural and manmade disasters can cause collapse of Transmission Line (TL) towers thus interrupting power transmission. Permanent restoration of towers will take several weeks, and hence temporary solutions such as Emergency Retrieval System (ERS) - temporary modular structures are used to restore the power within 2-3 days. ERS technologies available across the globe are very expensive. CSIR-SERC has developed an indigenous technology to produce cost-effective ERS suitable for 33 to 800 kV transmission lines.

ERS as an indigenous technology for quick restoration of power lines during tower failure events minimizes the monetary losses for power companies as well as loss of service to consumers. It is an import substitution providing the manufacturing opportunities to Indian industries.
