Abstract

A pulsed electroacoustic method (PEA) system with phase-resolving capability has been developed to measure space charge distribution at any phase angle of applied AC voltage in water-treed polyethylene. By comparing the observed charge distributions with theoretically predicted ones, it has been shown that the interfacial polarization due to the difference in conductivity between the treed and the untreed regions predominates the space charge behavior.
