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.

System and method for detecting voltage dependence in insulation systems based on harmonic analysis

A system and method of testing a power system component is disclosed. The system and method comprises coupling a test set to the power system component and stimulating the power system component with a frequency sweep signal. The method also comprises capturing a response of the power system component to the frequency sweep signal, wherein the response relates to frequency and mapping the response to an estimated response, wherein the estimated response relates to temperature. The method also comprises evaluating the power system component based on the estimated response.
