Polarization phenomena in synthetic polymeric insulators

It is shown that studies of absorption current, TSDC (thermally stimulated discharge current), and TTC (thermal transient current) provide useful information on dielectric polarization in synthetic polymer insulation. Particular results are presented on the time dependence of charging and discharging currents in polypropylene over the temperature range 87-373 K at a constant field of 6.67*10/sup 7/ Vm/sup -1/ and thermally stimulated discharge current spectra in polyetherether ketone charged at room temperature in nitrogen gas.<
