dc.description.abstractPartial discharge (PD) monitoring is essential for insulation diagnostic of high voltage power transformers. PD activities can generate electromagnetic waves in the ultra-high frequency (UHF) range. The signals captured from several antennas installed inside the transformer can be analyzed to determine their time of arrival (TOA) and time difference of arrival (TDOA). Then by solving non-linear triangulation equations, the position of the PD source can be found for corrective action. This paper examines the effect of the sensor position on the S-parameter regarding the UHF sensor performance for PD detection. A comparative study of the methods in terms of PD localization based on the UHF method is then carried out. Acoustic, UHF and HFCT sensors are applied in the experiment. The results show that the transformer tank boundary can affect the sensor performance in capturing the signal and the acoustic-UHF triggering method has the highest level of accuracy.
