| Abstract | The authors explored the thermal decomposition characteristics of perfluoroisobutyronitrile–carbon dioxide (C4F7N–CO2) gas mixture as eco-friendly dielectric medium. The main by-products and decomposition mechanism of C4F7N–CO2 gas mixture under different temperature and gas pressure conditions were revealed and analysed. It was found that the thermal decomposition of 6%C4F7N–94%CO2 gas mixture starts at about 350°C (0.15 MPa), producing C3F6 and CO first. Some other characteristic by-products such as CF4, C2F6, CF3CN, COF2 and (CN)2 could also be detected at higher temperature. The yield of C3F6, (CN)2 increased with the temperature (lower than 450°C) first and then decreased when it reached to 500°C. While the yield of CO, C3F8, COF2 and CF3CN increased with temperature (350–550°C). The generation of CF4 and C2F6 begins at temperatures higher than 500°C, which can be used as the feature component of severe overheating fault. The thermal decomposition amount and by-products yield of C4F7N–CO2 gas mixture slowed down with the increase of gas pressure, indicating that C4F7N–CO2 gas mixture is quite suitable used at high-pressure equipment, especially high-voltage devices such as gas insulated switchgear. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
