| Abstract | Composite insulators are widely used in transmission lines. Performance degradation of material is more and more urgent with operation time increases. In China Southern Power Grid, some composite insulators in-service suffer partial abnormal temperature rise which has been a serious potential hazard to operation of transmission lines. In this paper, a 500 kV AC composite insulator with partial abnormal temperature rise, was analyzed. By dissecting these insulators, FRP rod corrosion with varying degrees were found along the string. After that, chemical compositions on FRP rod corrosion surface were examined by XPS (X-Ray Photoelectron Spectroscopy). Test results showed that the basic elements, carbon, nitrogen and oxygen changes according to certain rules and the chain number of Si-O increases when corrosion degree aggravate. Analysis on change of chemical element reveals that the FRP rod corrosion of the composite insulators with partial abnormal temperature rise is mainly due to oxidation. |

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.
