| Abstract | There are some characteristics for the arrangement schemes of surge arrester for ± 800 kV UHVDC transmission line converter station. One of them is that some additional arresters have been introduced to limit over-voltage further at several special locations within the converter station, including an A2 arrester which protects the valve side of highest potential converter transformer in ± 800 kV UHVDC project converter station. Aiming to Yunnan-Guangdong ± 800 kV UHVDC project, mainly the analysis and studies concentrating on the necessity of A2 arrester has been performed in this paper. Some typical fault cases have been chosen to calculate the over-voltage generated at the relative positions of converter station under with and without A2 arrester respectively. The results show that the scheme with A2 arrester can protect directly the valve-side of the converter transformer at the highest potential and reduces the insulation level of valve-side equipment effectively, which results in the production costs and manufacture difficulties will be reduced, and therefore this scheme is quite intuitive and reassuring [2]. |

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.
