| Abstract | Gas insulated transmission line (GIL) is an advanced power transmission mode. Since the extension of this kind of equipment is relatively long, the grounding design and layout of the GIL will have a direct impact on personal safety and the stability operation of equipment, which should be given full attention. In order to ensure the safe and stable operation of GIL, it needs reasonably design and arrangement of the integrated grounding system in the GIL pipelines. This study designed corresponding grounding scheme for the integrated grounding system of underground GIL pipelines combined with a 550 kV/4000 A GIL. The corresponding simulation model of the integrated grounding system was established with specific parameters of the GIL. The calculation results show that the grounding resistance of the integrated grounding system is 0.217 Ω, which is less than the grounding requirement value of 1 Ω, and it reduces 28.9% compared with the simulation model without considering the natural grounding body. In addition, the step voltage and touch voltage are reduced by 79.91 and 48.97%, respectively. The research results can give some references for the integrated grounding system design of GIL engineering. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
