| Abstract | Based on the traveling wave theory, the process of transient traveling wave in non-solidly earthed network has been analyzed. The analysis discovers that the traveling waves in the healthy lines are mainly composed of the refracted traveling waves at the bus bar, which are generated from the backward traveling wave of the fault line, then the energy of the refracted traveling waves is the main portion of that in the healthy lines; the energy of the transient traveling waves in fault line is much more than that in the healthy lines, and a thought that peak values are used to express the traveling wave energy is proposed. Considering the complicated conditions in practical field, line selection error may occur only using one criterion, especially in high resistance fault and zero crossing fault. Fractal theory has the superiority in signal fluctuation detection, a combined criteria based on energy of traveling wave and fractal theory is composed in this paper. The ATP simulation shows that the combined criteria improves the robustness, and has high adaptability. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
