Abstract: A system includes a dry contact with a first pair of switchable electrodes, a wet contact with a second pair of switchable electrodes, an arc suppressor, and a controller circuit operatively coupled to the arc suppressor and the first and second pairs of switchable electrodes. The controller circuit is configured to detect a failure of the wet contact and determine a stick duration associated with the first pair of switchable electrodes. The stick duration is based on a duration between an instance when a coil of the dry contact is deactivated and an instance of separation of the first pair of switchable electrodes during deactivation of the coil. The controller circuit generates, in-situ and in real-time, health assessment for the first pair of switchable electrodes based on a comparison of the determined stick duration with an average stick duration associated with a window of observation.

Abstract: A power contact health assessor system includes a pair of terminals adapted to be connected to a set of switchable contact electrodes of a power contact and a contact separation detector configured to determine a time of separation of the set of switchable contact electrodes during deactivation of the power contact. The system includes a controller circuit operatively coupled to the pair of terminals and the contact separation detector. The controller circuit is configured to determine within a first observation window, a plurality of contact stick durations and an average contact stick duration. One or more additional observation windows with corresponding average contact stick durations are configured. A health assessment for the set of switchable contact electrodes may be based on a subsequent contact stick duration for a contact cycle after the first observation window and the corresponding average contact stick durations for the one or more additional observation windows.

Abstract: A power contact EoL predictor includes a pair of terminals adapted to be connected to a set of switchable contact electrodes of a power contact; a power switching circuit configured to trigger activation of the contact electrodes based on a first logic state signal or deactivation based on a second logic state signal; a contact separation detector determining a time of separation of the switchable contact electrodes of the power contact during the deactivation, and a controller configured to generate the second logic state signal to trigger the deactivation, and determine a stick duration associated with the set of switchable contact electrodes. The stick duration is based on a difference between a time the second logic state signal is generated and the time of separation during the contact cycle. The controller generates an EoL prediction for the contact electrodes based on the determined stick duration for multiple contact cycles.
