| Abstract | This paper presents detail analysis on transducers used for online monitoring system for electrical apparatus. Transducers are the key components of the online monitoring system; they play important roles on the stability and accuracy of monitoring results. Two types of transducers are discussed in this paper - the transducers used for dielectric loss angle measurement and the ones for partial discharge measurement. Basically their characteristics can be derivative from a uniform equation according to the materials used and structure, but the aspect differs from the frequency domain and time domain analysis. The transfer function of the transducers is put forward, the phase-frequency, amplitude-frequency characteristics are discussed and the time-domain response is concluded from unit pulse response convolution. The structure, shielding are also mentioned. For the characteristics may be changed with the temperature shift, the error analysis is implemented to compensate the result. The results of the field test have proven the stability and feasibility, and these transducers can be used for electrical apparatus insulation online monitoring. |

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.
