| Abstract | The third harmonic has caused much power quality problem in the neutral of distribution system. Salient pole synchronous generator has been recognized as one of the triplen/third harmonic sources. This research is aimed at studying the characteristic of third harmonic from generator flowing through the load directly, via transformer and shunt connection to rectifier. Lab scale experiments have been conducted to vary load impedance and transformer winding configuration. When generator is connected directly to a combined resistive and inductive load, the third harmonic current and voltage depend on the load impedance magnitude and phase angle. Since the third harmonic voltage produced by generator are in phase or zero sequence in nature, the third harmonic current depend on transformer winding configuration, the load impedance magnitude and phase angle. When full-wave bridge rectifier is shunt connected between generator and load, the third harmonic current at both rectifier and load are actually coming from generator that depend on load impedance magnitude and phase angle. It is recommended that the study on third harmonic voltage and current propagation from generator should be done by performing harmonic measurement and analysis at all parts of the network. Third harmonic voltage and current magnitude alone may not give correct indication to their severity because they are vector quantity and rely on zero sequence network, load impedance magnitude and phase angle. |

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.
