在点对面电极系统中，采用重复频率为25 Hz的准矩形电压脉冲，研究了蒸馏水和低导电性水（σ<15µS cm-1）中脉冲电击穿的瞬态状态。在18.5- 20kv电压区间内观察到两个单独的电流脉冲。暂态状态的出现受到存储电容器C4 nF的最小电容的限制。第一个电流脉冲的时间滞后不受存储电容器电容的明显影响，而第二个电流脉冲的时间滞后随着电容的增加而增加。头部电场的畸变和由于静电电荷在气体通道内壁上的积累而导致的先导通道电阻的增加是在瞬态状态下最可能有效的两种机制。在这种情况下，OH自由基产生的增强可以从光谱观察中推测出来。
The transient regime of pulsed electrical breakdown in both distilled and low-conductive water (σ<15 µS cm-1) has been investigated in a point-to-plane electrode system using quasi-rectangular voltage pulses with a repetition frequency of 25 Hz. Two individual current pulses were observed within the interval of voltages of 18.5-20 kV. The appearance of the transient regime was limited by the minimal capacitance of the storage capacitor C4 nF. While the time lag of the first current was not apparently affected by the capacitance of the storage capacitor, a growth in time lag of the second current pulse was observed as the capacitance was increased. The distortion of the electric field at the head and an increase of the leader channel resistance due to accumulation of the electrostatic charge on the inside wall of the gaseous channel are two most likely mechanisms effective in the transient regime. The enhancement of OH radical production in such a regime can be surmised from spectroscopic observations.
