System and Method for Detecting Voltage Dependence in Insulation Systems Based on Harmonic Analysis

摘要

A method of testing an insulation system is disclosed. The method comprises coupling a first test lead to a first conductor, the first conductor at least partly isolated by the insulation system and coupling a second test lead to a second conductor or a ground. The method further comprises applying a test signal to the first test lead, receiving a test response from the second test lead, and analyzing the test response from the second test lead to determine a harmonic content of the test response. The method further comprises, when the harmonic content is equal to or greater than a predetermined threshold, determining that the insulator system has non-linear properties.
