内容記述 | We investigated propagation properties of Lamb waves in GIS tank using time-frequency analysis to diagnose insulation performance of GIS. We measured the acoustic signals excited by a metallic particle colliding with the tank sheath, and those emitted by partial discharge in GIS as well. The Wavelet Transform was applied to decompose the wave data into its timefrequency components. As the result, it was confirmed that Lamb waves with the dispersive property of the velocity are excited and the waves propagate spirally along the tank wall due to the cylindrical structure of the tank. Taking these results into consideration, we proposed a new technique for identification of the defect location in GIS based on the time-frequency analysis of the acoustic waves using the Wavelet Transform. | |||||||||||||||||
