Abstract

A new method for the measurement of high field ac conduction current in polymeric insulating materials is developed by using an unbalanced operation of the current comparator type high field tan /spl delta/ - capacitance bridge and the deconvolution technique. The new method was checked by the known input signal to the bridge. Finally this technique was applied to the ac conduction in low-density polyethylene films.
