Originální abstrakt

One of the crucial aspects of high voltage power transformer is the quality of its dielectric oil filling. Partial discharges represents significant problem which can lead to serious transformer failure and accident. Variety of methods for early detection of partial discharge has been developed over time. The most progressive is the UHF method. The article reports on the results obtained by the application of new Discrimination of Disturbed Acquisition detection approach within the UHF method. Further, proposal of novel modification of sensors are described. The approach consists in the adjustable signal filtration before processing, which can significantly improve the reliability of partial discharge signal identification.
