| Abstract | An accurate electric model of the earth is important for many applications related to electric traction and distribution systems like the stray current. As the DC electrified traction system is the potential source of the stray current, the operation of traction vehicles such as trains and trams makes the emergence of stray currents in the area of rails and under the rails. These leakage currents can adversely affect pipelines or cable lines near the rail [7][11]. There exist numerous models which have been modeled this phenomena [2][4][11], all models are based on one Dimensional earth structure, actually the nature of the earth underneath of the railways could not be represented as a homogeneous medium. The characteristics of the soil vary depending on the location and locally with depth, and a homogeneous earth model might be inadequate. [1] shows that even the multi-layered earth models are not reliable to be the base of the calculation of several applications related to the earth and grounding systems and it is required an accurate earth model which can give a better overview of whole structure of the underneath ground. In this work after a general presentation of the existing and proposed earth model, it is presented a comparison between the calculation of the stray current propagation based on one and 3-Dimensional earth model. |

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.
