Measurement and diagnostics of electrical signals under high voltage repetitive nanosecond-pulses

In order to obtain experimental parameters of gas breakdown under repetitive nanosecond-pulses, this paper introduces measurement and influencing factors of incident voltage and discharge current, and describes repetitively stressing time which is peculiar to repetitively nanosecond-pulse breakdown. The response bandwidth of measurement component, intermittent electromagnetic interference, and transient high-frequency oscillation when insulating gas gap is brokendown can affect the measured results of electrical signals, especially lead to a short-duration disturbance on the measured signals. The wavelet soft-threshold denoising method can reduce the interference effectively. Based on the response measurement of current diverter, the deconvolution using Wiener filtering theory can compensa
