"10617" . "The proposed article will present a new approach to detection of very weak electromagnetic signal, which is generated by partial discharge (PD). This approach is a part of radiofrequency method, known as ultra-high frequency (UHF) method. The UHF method is utilized for detection, activity quantization and localization of PD in high-voltage power transformers. The UHF method is the most advancing method for this type of transformer diagnostic. The state of the art in instrument technology allows real-time acquisition and processing of pulsed broad band signals together with 3D localization of PD occurrence. The UHF method is based on measurements of electromagnetic waves in UHF spectrum produced by PD. Typical spectrum of the PD UHF signal ranges from hundreds of MHz to units of GHz. The UHF signal is detected by sensing heads that enter the transformer through its casing. Sensing heads, which were developed at Brno University of Technology (BUT), contains antennas and a set of high-frequency component"@en . "Steinbauer, Miloslav" .
