| Abstract | With industrial growth it has become necessary to monitor the condition of three phase squirrel cage induction motor, as it is the most sensitive part in the production line of industry. Special attention has been given to non-invasive methods which are capable of detecting fault by acquiring major data without disassembling the machine. The present paper discusses a few basic yet important aspects of condition monitoring of the induction motor based on investigation of Concordia patterns obtained through the Park's transformation of stator currents. The current Concordia pattern is greatly influenced by the internal condition of the motor as well as the external supply condition. The prime focus of the diagnostic technique is on identifying the change in shape of current Concordia patterns and shifting of its major axis orientation corresponding to stator inter-turn fault conditions with varying severity and varying power quality problems of supply system, like voltage sag and swell. This proposed method can be efficiently employed to discriminate and assess the operating condition of induction motor due to internal stator winding fault and power quality problems of the external supply system. |

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.
