Abstract
This disclosure describes systems, methods, and apparatus for determining a relay delay for a relay of a relay device used to switch AC power to and from a load. The relay delay can be pre-determined as a model or polynomial including variables for temperature and age, such that the switching instructions can be sent to the rely a relay delay before a zero crossing of the AC signal that the relay is switching, and where the relay delay accounts for temperature and age of the relay in real time or near real time.
