| Abstract | Traditionally, a coordination scheme of circuit breakers (CBs), reclosers, and sectionalizers using time current curves has been widely used for radial networks with a single supply site or loop networks with two distribution feeders tied by a normally open tie recloser. However, conventional schemes that rely only on current information reclose onto a fault. This major drawback occurs when a normally open tie recloser closes onto the other supply of the system because the load side recloser closest to the fault location is not able to locate the fault condition. This paper proposes a new circuit breaker, recloser, and sectionalizer coordination scheme, referred to as the voltage, current, and time (VIT) scheme. Integral parts of the VIT scheme are strategically applied counters and timers on the protection devices. The VIT protection devices can detect a fault condition from both upstream and downstream of a fault location and assist in isolating only the faulted part of the circuit. |

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.
