System and method with timing self-configuration

摘要

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.

1. A method of operating an automatic transfer switch to switch an electrical load from one power source to another power source, comprising:
measuring one or more characteristics of a switching circuit in the automatic transfer switch; determining a value of one or more delays for the switching circuit, wherein the one or more delays comprise a delay between a control event and a closing of one or more relays of the automatic transfer switch, wherein the one or more delays are determined based, at least in part, on at least one of the measured characteristics of the switching circuit; providing electrical power to the electrical load via the automatic transfer switch; subsequently measuring at least one of the one or more characteristics of the switching circuit in the automatic transfer switch while electrical power is being provided to the electrical load via the automatic transfer switch; adjusting the value of at least one of the one or more delays based, at least in part, on the at least one characteristic of the switching circuit measured while electrical power is being provided to the electrical load; and operating the switching circuit to close one or more of the relays in the automatic transfer switch, wherein the timing of the closing of at least one of the relays is based, at least in part, on the adjusted value of the at least one delay.
