| Abstract | The traditional PD detection methods could not meet the requirement of PD detection for power transformers (especially for online monitoring), because of their narrow measuring band, poor anti-interference performance and less information. The ultra-high-frequency (UHF) PD detection method has been newly put forward. According to the detection experience in GIS and the discharge characteristics in power transformers, the authors have designed and developed a kind of UHF sensor, namely, the two-wire Archimedian planar spiral antenna. The effective frequency range of the sensor is 500-1500 MHz. The characteristics of this sensor are analyzed by antenna theory and measured in the laboratory, and it is shown that the sensor has superior performance characteristics. In this paper, the sensor is also applied to measure PD signals in transformer oil, and results show that it can be used to detect UHF PD signals in an effective frequency band, which is very useful for laying foundations on setting UHF PD detection in power transformers. |

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.
