摘要

所有液体都表现出非零导电性，表明电荷的存在。虽然通常被认为是均匀分布的，但这些电荷受到界面（双电层）或外部电场的影响。它们的局部积累会影响电力设备的性能。很少有精确的方法来测量液体中的电荷分布。prime研究所一直在调整固态技术，如压力波传播（PWP）方法，用于液体。这使得人们能够观察到介电和导电液体在直流电场下电荷在空间和时间上是如何重组的。

PWP measurement of charge distribution in dielectric and conductive liquids under DC electric field

All liquids exhibit non-zero electrical conductivity, revealing the presence of electric charges. Though often considered uniformly distributed, these charges are influenced by interfaces (electrical double layer) or external electric fields. Their local accumulation can affect the performance of power equipment. Few precise methods exist to measure charge distribution in liquids. The PPRIME Institute has been adapting solid-state techniques, such as the Pressure Wave Propagation (PWP) method, for use in liquids. These have enabled the observation of how charges spatially and temporally reorganize under a DC electric field in dielectric and conductive liquids.
