| Abstract | The DC electric field strength is an important electromagnetic environment parameter of the high-voltage direct current (HVDC) transmission line. Measurement results of the space electric field are dramatically affected by the size and the potential of the sensor. In addition, the battery-powered solution of electric field sensor (EFS) is not feasible, for the reason that in the high-voltage electric field environment, the replacement of the battery will bring security risks to the power system and workers. The wireless energy supply solution not only solves the problem of potential isolation of the sensor, but also ensures that the sensor can work continuously. Various wireless power transmission systems (WPTSs) were compared. Microwave wireless power transmission system (MWPTS) was selected as the power supply of EFS. The key boundary conditions of MWPTS were determined. Two microstrip receiving antennas were designed in this article. A good performance antenna with high permittivity substrate was designed, realising 4.26 dB gain with the area of 1 cm2 at 5.8 GHz. The antenna meets the energy requirements of the EFS which is 10 m far from the source. |

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.
