Abstract:
A system includes a control module and a monitor module. The control module selectively operates a component of the system in an ON state. The system receives power from an electrical grid. The monitor module selectively detects a fault event of the electrical grid in response to (i) an amount of current drawn by the component or (ii) a voltage of power received by the component. In response to detecting the fault event, the control module switches the component from the ON state to a second state, determines a first delay period according to a random process, identifies an apparent conclusion of the fault event, and in response to the apparent conclusion of the fault, waits for the first delay period before switching the component back to the ON state. The component consumes less power in the second state than in the ON state.
