| Abstract | This study evaluates the performance of a permissive overreach protection scheme proposed to ensure rapid fault clearance, in a real example of a medium-voltage (MV) distribution loop by one of the largest European Distribution System Operators. The MV loop and the protection devices including the proposed signal comparison schemes have been modelled in detail in the power system analysis software DIgSILENT PowerFactory. The evaluation has been performed using steady-state short-circuit calculations and electromagnetic transient simulations. This analysis reveals limitations in the permissive overreach scheme based on the zero sequence phase comparison directional logic in the case of cross country faults. Alternative solutions, such as phase, zero sequence and negative sequence magnitude differential protection schemes, have been assessed. A permissive overreach protection scheme based on the negative sequence phase comparison directional algorithm has also been considered. |

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.
