  • Circuit protection and control device simulator
    Patent number: 8255200
    Abstract: A power circuit protection and control device simulator emulates in real time identical circuit protection and control functions performed by the actual device being simulated and generates real time simulated operational information concerning at least one of the device or the power circuit. A human-machine interface, such as through a web browser, allows a user to input power circuit operational parameters, such as motor current and load, and device variable circuit protection and control operational parameters, such as trip class, ground fault detection or phase unbalance protection. The simulator displays in real time simulated operational information on the human-machine interface. The simulator may be used to simulate operation of an electronic overload relay and an electric motor controlled by the relay.
