Simultaneous Measurements of Transit Space Charge Distribution and External Circuit Current up to Electrical Breakdown in LDPE Film

摘要

In this paper, we report an investigation using pulsed electroacoustic (PEA) method on electrical breadown phenomena in a low-density polyethylene (LDPE) film. A space charge distribution and an external circuit current were simultaneously measured up to electrical breakdown in a 100μm thick LDPE film with a semi-conducting electrode under DC voltage. An electric field distribution and conduction current were estimated based on these experiments.
