| Abstract | Electrical power transmission system requires the use of circuit breakers with increasing breaking capacity. At present circuit breakers are to be installed on 245 kV to 760 kV power system with short circuit ratings upto 63kA. To test high voltage CBs, direct testing using the power system or short circuit alternators are not feasible. The testing of high voltage CBs of larger capacity requires very large capacity of testing station. To increase testing plant power is neither an economical nor a very practical solution. Therefore indirect methods of testing are used for testing of large CBs. Synthetic testing is an alternative equivalent method for testing of high voltage circuit breakers and is accepted by the standards. This paper presents a comprehensive review of TRV rating concepts, standard TRV envelopes, types of synthetic test circuits used for high voltage circuit breakers. Design and simulation of 4-parameters TRV synthetic testing circuits is done by using PSIM simulator. Three different 4-Parameters TRV circuits are simulated for a 420 kV rating circuit breaker for comparison purpose. Design optimization is also done to reduce the energy required by the capacitor banks. The results obtained by using different circuits have been discussed and compared with the required results according to IEC standards in the paper. The comparison is made on aspects of equivalence, operation, required capacitive energy and applicability. |

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.
