| Abstract | Summary form only given. During the interuption of a short circuit current with a circuit breaker, an arc is formed in order to eliminate the energy stored in the electrical network. When the operation is performed by a miniature circuit breaker, the arc moved from an ignition area towards a quenching area. In some cases, a phenomenon of arc re-ignition outside the quenching area and far from it (several centimeters) may occur. The so-called back commutation increases the interruption time and the energy expended in the breaker and as a result restricts its efficiency. Our works deal with the study of the arc restrike mechanism. A model breaker has been designed to generate arc restrikes in the ignition area under well known conditions. Typical breaking time and peak current intensity are respectively 10 ms and 5 kA. The set up enables the diagnostic evaluation of very small current (down to several tens of amps) in the limited critical region where the arc restrikes, owing to a novel high sensitivity current measurement device. |

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.
