Abstract In order to explore the method of high sensitivity detection for mobilized metal particles in gas insulated station (GIS)equipment, the effect of voltage waveform on free metal particle has been studied.The experimental platform of mobilized metal particle’s partial discharge has been set up in the laboratory, and mobilized metal particle partial discharge phenomena has been measured under standard lightning impulse voltage, standard switching impulse voltage, and AC voltage respectively.The characteristics partial discharge under different voltage waveforms have been studied, so that the scatter plot and the histogram in different test stages has been acquired under the impulse voltage.The results of the study show that, under the three kinds of voltage waveforms, i.e.the standard lightning impulse voltage (LI), the standard switching impulse (SI), and the AC voltage, the partial discharge inception voltage of the standard lightning voltage is the lowest one, which provides sensitivity for free metallic particles detection.With the increase of the standard lightning impulse voltage, the discharge pulse number becomes more obvious in the wave tail of the standard lightning impulse, but the discharge pulse number in the wave front of the standard lightning voltage remains one.With the increase of the standard switching voltage, the discharge amplitude in the wave front and the tail have become large and the number of discharge is increased, and the number of discharge at the wave front increased more significantly.The characteristics of the q-t scatter plot, the q-Δt/Δu scatter plot, and the N-Δt/Δu histogram are regular, which can be used as the characterization spectrum to indicate the serious degree of GIS mobilized metal particle discharge.
