The predetermination of the A-C. behavior of dielectrics

CHARGE and discharge currents of any type of dielectric under continuous potential make it possible to predict accurately the loss, power factor, and capacity at 60 cycles. This is done by an empirical determination of the equation for the relaxation function of the dielectric at a given temperature, followed by the application of von Schweidler´s method. The method developed is available at any frequency, provided the continuous potential charge and discharge currents may be measured over initial time intervals comparable with the alternating period.
