Synopsis 1200 kv UHV transmission technology is being developed for the first time in India. Insulation Co-ordination was the biggest challenge for selection of technical parameters of various equipments like Surge Arrestors, Transformers, Circuit Breakers, and Instrument Transformers etc. In this conference various issues related to insulation coordination, selection of technical parameters, development of various equipments by manufactures, testing at labs & field etc shall be discussed / deliberated. Renowned Experts from world over are expected to share critical aspects of designing of UHV technology. While designing, construction and operating a station at higher voltage, field test is crucial. Field handover test, commissioning test and prventive tests are to be given special considerations.
