DOI: 10.1109/tim.2022.3192282
Abstract: This article proposes a method that indirectly measures the contact erosion of alternating current (ac) contactors via mapping electrical signals to the contacting alloy erosion condition which is represented by the accumulated contact mass loss… read more here.
