SYSTEMS AND METHODS FOR DETECTING WELDED CONTACTS IN A SWITCH SYSTEM
Systems and methods are provide for detecting weld relay devices within a switching device by: closing one or more first relay devices, wherein the one or more first relay devices are configured to selectively connect and disconnect a first phase of electric power from a power source; opening one or...

| description | Systems and methods are provide for detecting weld relay devices within a switching device by: closing one or more first relay devices, wherein the one or more first relay devices are configured to selectively connect and disconnect a first phase of electric power from a power source; opening one or more second relay devices and one or more third switches; detecting whether there is electric current through the one or more second relay devices; and in response to detecting that there is electric current through the one or more second relay devices, determining that the one or more second relay devices are welded. |
