| Abstract | Nowadays, Sweep FRA becomes a common measurement tool used to identify the transformer condition. The standard for this technique and how to interpret the result has been released by CIGRE and IEEE. PT PLN P3BJB is operating 787 transformers from various voltage ratios. Most of the transformers are 150/20 kV (64.4%) and there are 35 transformer s operated in 500/150 kV. Each of the transformers is provided with OLTC to adjust the output voltage. As a common knowledge, every transformer has its own RLC value. The RLC value will be influenced by some factors, i.e. natural aging, low voltage side disturbance or even tap position. If the tap position changing, the number of turn will be different, means RLC value will be different. Based on this condition, interpretation should be done carefully. In this paper we will describe the characteristic of SFRA measurement result for Inter Bus Transformer (IBT) 166 MVA operated in 500/150 kV. According to measurement results, by changing the tap position, the pattern of SFRA result for IBT 166 MVA will be different in frequency range 1 kHz - 100 kHz, especially for full tap winding and without tap winding. |

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.
