| Abstract | The 110 V lead-acid battery pack is widely used as the DC power supply for the load control of power plants. If the low-voltage DC circuit breaker (LVDCCB) at the DC side of its charging device cannot operate in time when the fault current is flowing in charging loop, there will be of harmfulness to the safety and the durability of the battery pack. The plasma theory is applied to analyse the arc mechanism based on the voltage, the current and the power waveform of LVDCCB when it breaking. Then, an arc extinction is developed by assembling an additional device to LVDCCB. The device, connected to the contacts of LVDCCB, includes an insulated-gate bipolar transistor series branch, an energy-absorbing branch, a transfer switches branch, and a drive circuit. The test shows that the break time of LVDCCB, assembled with the additional device, is significantly shortened than that of the original. |

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.
