Abstract
Discharge currents and degradation of polyethylene from high dc electric field stress in air were investigated. a positive point-to-plane configuration was used with thin polyethylene samples on the cathode surface. Voltage, spacing, and relative humidity were independent variables. the surface chemistry and resistivity of the samples evidence changes as degradation occurred. This changing boundary condition affected the gaseous discharge. Both electrical and physical measurement techniques have been utilized to characterize the degradation. Electrical measurements include surface resistivity measurements, pulse train recording of partial discharges, and continuous current measurements. Physical measurements include X-ray photoelectron spectra (XPS), atomic force microscopy (AFM) roughness measurements, and Fourier transform infrared (FTIR) spectroscopy spectra.
