| Abstract | Grounding fault current distribution and the reduction factor of a power cable is an important parameter for the design of substation ground grid, the correct estimation of the safety conditions (step and touch voltages) in the supplied substation and the interference to the communication system nearby. In this paper, a simplified equivalent model is presented for three single-core cable sheaths, which are two-ends grounded. Both of the cable sheaths with or without applied cross-bonding connection are discussed here. Based on this, the paper presents an original analytical procedure for determination the ground fault reduction factor when a ground fault happens in the substation supplied by HV cable network. The method is proved to be a practical and precise one for evaluating the ground current distribution and the reduction factor in HV cable system |

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.
