| Abstract | This paper discusses methods to mitigate contamination and moisture ingress into pad-mounted switchgear. Pad-mounted switchgear is installed and forgotten with little if any maintenance over its life cycle. Site-specific environmental issues may range from mild to severe contamination conditions. Contamination and moisture ingress if severe can lead to premature unit failure. This paper discusses three methods of mitigating contamination and moisture ingress: (1) basic switchgear design concepts, (2) moisture barriers (3) energized cleaning using propelled dry-ice pellets. As a product, the original designs of metal-enclosed switchgear first appeared in the 1930s and, as with every product life cycle, there were initial difficulties to overcome. But, in the case of switchgear, one dual problem has continued over its life cycle. Specifically, the control of contamination and moisture ingress has been critical to long-term survival. This problem became even more difficult as the off-shoot pad-mounted switchgear installed over an open pit became a widely used product in electric utility power distribution systems and has subsequently moved into the commercial and industrial sectors. |

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.
