Abstract
A method of operating an automatic transfer switch to switch an electrical load from one power source to another power source includes measuring one or more characteristics of a switching circuit in the automatic transfer switch. A value of one or more timing variables is determined based on the measured characteristics of the switching circuit. The switching circuit is operated to close relays in the automatic transfer switch. The timing of closing of the relays is based on the value of the timing variables.
