ABSTRACT:
A method for measuring degradation of electrical power system device insulation utilizes a conductive composite sensor. A selected polymeric matrix of the conductive composite provides a sensor resistance response that correlates to the mechanical degradation of the insulation. The sensor may be embedded in the windings, core or stator of the electrical power system device and wired to a connector on the electrical power system device for interrogation by an ohmmeter.
