Witryna18 mar 2024 · This paper presents experimental results of high-current impulse tests on six ground electrode configurations. A high impulse current generator is employed to inject different magnitudes of current into these rod electrodes, under both positive and negative impulse polarities. The effect of increasing the number of rod electrodes, … WitrynaThe particle effect on breakdown voltages also becomes more prominent when the effective stressed area/volume of the electrode configurations is increased. …
Witryna17 paź 2024 · Electrical breakdown of tap water (350 μ S·cm −1) under sub-millisecond pulses (0.5 ms) with a gap distance of 3–35 mm has been investigated. It was found that the gap distance has a great influence on the polarity effect of underwater electrical breakdown, including breakdown mode, breakdown voltage, and pre-breakdown …
