ABSTRACT:
An apparatus for evaluating the performance of a dielectric substance includes: at least a pair of electrodes disposed in contact with the dielectric substance to be measured; a power supply for applying a pulse voltage to the electrodes; a current detector for detecting a transient response current flowing between the electrodes dependent on the component of the dielectric substance disposed between the electrodes; and a signal processor for evaluating the performance of the dielectric substance. The performance evaluation may be performed based on at least one of a peak value of the transient response current at a certain period of time, a difference between the peak value and a value at a fixed period of time after the peak value, and a ratio of the peak value to the difference between the two values. With this method and apparatus, the performance of the dielectric substance can quantitatively be evaluated.
