  • Key interlock system and method for safe operation of electric power distribution system
    Patent number: 9748797
    Abstract: Key interlock systems and methods are described for safely carrying out a closed-transition procedure in an electric power distribution system in which two load busses that can be separately powered by the same power source or by two different power sources can be connected together via one or more bus tie breakers and in which a static transfer switch is used to selectively deliver power from one of the two different power sources to at least one of the load busses. Embodiments described herein prohibit access to a key that is required to close a bus tie breaker that connects the two load busses until at least a determination is made that a particular bypass breaker of the static transfer switch has been closed, thereby ensuring that both load busses are connected to the same power source.
