Even Order Harmonics as early detection of failure.
Even Order Harmonics as early detection of failure.
(OP)
This grows out of a statement made in the thread
thread238-340664: How to sum or calculate voltage or current harmonics component that are in parallel ?
I am wondering if monitoring or trending even order harmonics may be used to detect and then locate failing equipment. If an increase in even order harmonics is seen, then the problem may be located by drilling down through Power Distribution Centers, Motor Control Centers and then individual circuits to find the source of the problem.

Is this effect ever used in preventive maintenance?Quote (ScottyUK)
Even-order harmonics are usually a result of a problem - asymmetry in the firing delay angle being a common cause.
