Abstract

Paper describes new method of the estimation of the relaxation properties of dielectric materials based on the direct estimation dipole R,C parameters and from the decomposed isothermal current, which is represented by multiexponetial function. Proposed least mean squared optimization is resistant on the accumulation of error in the successive component estimation. Moreover takes into account mutual influence of parameters on the time constants and peak values of the exponential components.
