| Abstract | The current standards related to live working provide no determined path for equal potential working, in which only safety distance is referred, so that the works are often executed relying on the line maintenance experience. As high-voltage and strong space electrical field intensity exist in 1000 kV ultra-high voltage transmission lines, the real-time safe distance measurement is difficult to be conducted and the exhaustive full-scale experiments are difficult to accomplish due to the varied true tower models and lines. Simulation calculation is aroused for improving the efficiency of safety distance calculation and safety path planning during the process of importing and exporting the potential according to the different kind of tower and the actual line situation. Here, with the cup type iron tower and hanging basket mode, the electrical field intensity in and outside of screening clothes at different part of body while climbing tower and during equal-potential process are calculated, and then the safety distance, the combination gap, and the optimal path planning are carried out. The simulation results demonstrate that electrical field intensity meet safety requirements using the proposed planning path, which enriches the theoretical basis for the safety operation of ultra-high voltage live working. |

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.
