| Abstract: | Non-intrusive ultra high frequency detection method has been recognized as well established diagnostic tool for monitoring the condition of power transformers. This UHF method is considered as the best choice to sense the location of onsite partial discharges (PD's) in power transformer because of its good signal to noise ratio (SNR) and high sensitivity. The PD source location accuracy mainly rely on TDOA (Time differences of Arrival ) of PD source and the individual four uhf sensors or sensor array placed around the transformer tank. The location of PD source is evaluated by using PSO algorithm with the set of TDOA measurements from the experiment. |
