The Contemporary Definition of Complex Relative Permittivity

CODEN: JAIOAD

Abstract

ASTM D150 [Standard Test Methods for AC Loss Characteristic and Permittivity (Dielectric Constant) of Solid Electrical Insulation, 2004] is the standard for measurement of alternating current (AC). Aimed at an analysis of this standard and proceeding from the information transmission characteristic of the dielectric, the definition of ac complex relative permittivity εr(=Iac/I0=Qac/Q0=Cac/C00) is put forward anew. Faraday’s “relative permittivity” is a result of this definition under the specific condition (ω=0).
