| Abstract | This paper discussed the utilization of TEV-Transient Earth Voltage method in PD detection of GIS. The typical defect models in GIS concluding spikes fixed on HV conductor, voids defect in dielectric, suspended metals had been detected by TEV method, PMT, Rogowski monitor and PDCheck system synchronously. The TEV results showed good consistency with other three methods and had a good sensitivity. Based on this, phase distribution of PD, pulse number of different voltage level thresholds and the signal PD pulse characteristic had been obtained in this paper. In addition, the PD of needle-plane with very short gap had been detected under high frequency oscillating impulse voltage using this method. |

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.
