| Abstract | This paper presents an algorithm for high impedance fault (HIF) detection by phasor measurement units (PMUs) that are basic elements in wide area monitoring and protection systems (WAMPS). This method uses output current phasors of PMU for detection of HIF. At first, change of current detects by summation of errors between sampled data and estimated samples that are obtained from output phasors of PMU,Then in order to certain that this change is HIF, 3rd harmonic phase of fault current is used to discriminate HIF from normal condition such as load increasing/decreasing. Effects of transformer vector group on 3r harmonic phase are also studied. Several cases are simulated in EMTP&MATLAB to evaluate accuracy of method. |

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.
