使用改进的脉冲电声（PEA）方法对直流高压应力下苯乙酮涂覆的低密度聚乙烯（LDPE）中的空间电荷形成进行短间隔测量。该系统可以以小于一秒的间隔测量空间电荷的形成。使用该系统，在施加直流电压和极性反转期间，以 2 秒的间隔观察到苯乙酮涂覆的 LDPE 中动态空间电荷的形成。从实验结果发现，几秒钟内阳极附近出现了一个电荷包，随后该电荷包向阴极移动。
Short interval measurement of space charge formation in acetophenone coated low-density polyethylene (LDPE) under DC high voltage stress is carried out using an improved pulsed electro-acoustic (PEA) method. This system makes it possible to measure the space charge formation at intervals of less than one second. Using this system, a dynamic space charge formation in acetophenone coated LDPE was observed at 2 second intervals during the application of DC voltage and polarity reversal. From the experimental results, it was found that a charge packet appeared near the anode within a few seconds, which subsequently moved towards the cathode.
