| Abstract | In a high voltage power system, it is hard to measure directly and expediently the lightning currents accurately and safely. So aiming at solving the problem of accurate and safe measurement of the lightning current on the overhead transmission lines, a novel lightning current monitor system based on differential loop which has been widely used in the pulse power measurement technique is applied, which can measure the lightning current on overhead transmission lines contactlessly considering the actual running conditions in the 110kV level of transmission line. In this essay, the principle of the sensor for measuring lightning current and the design of the whole monitor system structure are introduced. In laboratory by using the high impulse current generator to simulate the lightning currents, the experiment results show that: for the 1.4m measured distance, through adjusting the sensor parameters and choosing reasonable shielding, the lightning current monitor system can collect the data of the high impulse currents accurately and completely, and the monitor system has the advantage of safety, strong anti-interference, endurance and accuracy. |

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.
