| Abstract | Grounding resistance could be reduced significantly with the usage of ground enhancing compounds in lightning protection systems. This paper presents the results of a series of field measurements on commercially-available ground enhancing compounds. It is the aim of this study to assess the behavior of ground enhancing compounds, which are widely used in grounding systems, in order to decrease the grounding resistance value. It is well known that most of the rise of potential of the grounding rod is determined by the soil resistivity surrounding the grounding rod and the magnitude of the applied current. As a result, the lowest feasible grounding resistance value is desirable, in order to provide the lowest impede path for fault currents to be dispersed into the earth, in the shortest time possible. For this purpose, five grounding rods were driven, each one of them, in different ground enhancing compounds. The measurement results are presented in relation to time and to rainfall. Furthermore, several thoughts, comments and proposals are presented about: a) the use feasibility of ground enhancing compounds, b) the choice of the suitable compound, in relation with the cost and the achieved grounding resistance value, c) the time and weather conditions influence on ground enhancing compound behavior. |

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.
