    Abstract

    Using an improved pulsed electroacoustic (PEA) system which is capable of measuring space charge distribution at minimum intervals of 25 μs, the charge distribution inside water-treed polyethylene (PE) was examined. From the results, the frequency dependencies of conductivity and permittivity were examined for water trees grown in PE. The conductivity of the water-treed region is found to be >1010 × higher than that of non-treed regions, while the permittivity increase is only slight.
