    Abstract

    The UHF partial discharge measurement technique is under research in order to be used for the detection, identification and localization of discharging defects within a power transformer. However, it requires installed dielectric windows on the transformer tank for the placement of the UHF sensors, a feature not available in all transformers especially old ones that have a higher risk of failure. Therefore, it is necessary to develop UHF sensors that can be used in the case of transformers without dielectric windows. In this paper such a sensor in its early design stages is studied, which can be inserted in a transformer from one of its valves.
