Abstract:
1. A method for analyzing at least one electrical contact pair electrically coupled in series wherein the at least one contact pair includes at least one of a contact that is electrically coupled to a line-side of the at least one contact pair, and a contact that is electrically coupled to a load-side of the at least one contact pair, said method comprising: electrically coupling the load-side contact and the line-side contact to electrical ground; applying a test voltage across the contact pair while the line-side contact and load-side contact remain electrically coupled to electrical ground; triggering a contact pair operation timer at a start of a test; detecting at least one of a first closure of the contact pair and a first opening of the contact pair using the test voltage; and determining the timing of the contact pair based upon the operation of the contact pair operation timer.
