Failure Analysis of Power Relays With Multiple Breaks in the Electrical Endurance Experiments.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Components, Packaging & Manufacturing Technology. Aug2022, Vol. 12 Issue 8, p1311-1317. 7p.

Abstract: Multiple breaks are favorable for arc extinguishment of relays switching heavy load. However, the existed asynchronous mechanical separation of contact pairs and associated unbalanced arcing behavior limit the electrical lifetime to some extent. In thi...
