| Abstract | Results of voltage sag measurements from five identified fault cases are presented in this paper. All the measurements were performed at one 110/20 kV substation on the 20 kV side. One fault was caused by a fallen 110 kV tower and two cases represent fallen trees on a 20 kV medium voltage feeder supplied by the substation in question. Another case concerns a fault, caused by a small animal, that occurred in a neighbouring MV network. The fifth fault case is an example of the most typical fault type, an earth fault in the 20 kV network where the fault itself causes no sagged voltages at low voltage customer locations but the circuit operations pertaining to the fault clearing procedure do. The measurement arrangements are explained and the measurement results of these particular faults are presented. By analyzing identified faults in this way, understanding of the system performance can be deepened. |

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.
