| Abstract | The lightning performance of overhead transmission lines is affected by many factors. Most of those factors are nature driven and are not predictable or controllable. Of those controllable factors affecting a line's lightning performance, the one that can be dealt with most cost-effectively is the transmission line's shielding. However, at some utilities, the design and selection of the line shielding method for transmission and sub-transmission lines operating at nominal voltages between 46 kV and 230 kV is typically relegated to a secondary level of importance because of the complexity of the calculations involved and an inherent reluctance to change. This paper presents a simplified method for optimizing the transmission line shielding angle to minimize the line's predicted lightning performance. The proposed method for optimizing the line's shielding angle relies on known formulas and procedures developed over the past four decades. The simplified method presented can be used by utilities in upgrading their current line shielding practices. |

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.
