ABSTRACT:
Methods, systems, and articles of manufacture consistent with the present invention provide for determining the environmental resistance of a wire insulation. The broadband impedance of the wire is obtained before and after the wire is exposed to an environmental condition. The real and imaginary components of the dielectric functions are then extracted from the broadband impedances. A tangent of a ratio of the imaginary component to the real component of the dielectric function of the wire prior to exposure is compared to a tangent of a ratio of the imaginary component to the real component of the dielectric function of the wire after to exposure. The two tangents are then compared to determine the environmental resistant of the insulation.
