| Abstract | This paper aims to study the electrical behavior of snow for the purpose of developing an analytical model. Laboratory tests on a snow-covered polymer insulator string were carried out under high alternative voltage. The voltage-current characteristics of snow were analyzed, showing that voltage across snow is a logarithmic function of leakage current depending on snow density and melted conductivity. It was also found that voltage across snow is almost in phase with the leakage current through it. However, the obtained results show that snow resistance decreases as voltage across it increases. An analytical relation between applied voltage and the current flowing through snow as a function of density and conductivity of water melted from snow is derived. There is good correlation between analytical and experimental results. |

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.
