Abstract
Multiple-arc analysis is used in conjunction with a generalized relaxation time distribution (GRTD) to derive an equivalent electric circuit model for dielectric materials that exhibit frequency dispersion. The validity of this new methodology is examined by comparing reported measurements of a.c. conductance and capacitance of a polymeric dielectric with those obtained from the equivalent circuit prediction. The values are shown to agree satisfactorily over the frequency range 100 to 850 kHz.
