| Abstract | Due to the importance of the hydroelectric project of 400 kV Tocoma for compliance with the requirements of demand, with high operational safety, we present the development of this work. Its objective consists in to analyze the behavior of the isolation of the transmission towers to the entrance of the bay of the substation due the impact of lightning on ground wire. We obtain the behavior of the line considering lightning of 5 and 20 kA and ground resistance at the foot of the tower of 0, 20, 100 and 400 Ω, using the simulation program PSCAD / EMTDC. The results show that none of the simulated cases are above the recommended level for line; however, to lightning of 20 kA and 400 Ω of resistance, the tension obtained of phase to ground is twice normal operation of the system, a value close to the limit let to the system. |

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.
