Abstract | In this paper a method for the broken rotor bar fault detection of induction squirrel cage machines is presented. This method is based on measurements and frequency analysis of the sum of the stator phase currents (the stator circular current) for delta connected windings. For the case of the star connected windings the stator neutral point voltage is measured and analyzed. A model of squirrel cage induction machine, which takes into account the stator windings and rotor cage layout, is used for theoretical investigations of the proposed method. Based on the theoretical investigations it has been found out that the spectrum of the stator circular current, and also the neutral point voltage, contains the rotor fault-related interharmonics. At the same time, these interharmonics are the largest components in the frequency spectrum. The proposed method has been experimentally verified and compared with the procedure based on the frequency analysis of the line current. |

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.
