Compressor protection and grid fault detection device
First Claim
1. A method comprising:
- selectively operating at least one component of a system in an ON state, wherein the system receives power from an electrical grid;
selectively detecting a fault event of the electrical grid in response to at least one of (i) an amount of current drawn by the at least one component and (ii) a voltage of power received by the at least one component;
in response to detecting the fault event, switching the at least one component from the ON state to a second state, wherein the at least one component consumes less power in the second state than in the ON state;
determining a first delay period according to a random process;
identifying an apparent conclusion of the fault event; and
in response to the apparent conclusion of the fault, waiting for the first delay period before switching the at least one component back to the ON state.

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.

16. A system comprising:
-
a control module that selectively operates at least one component of the system in an ON state, wherein the system receives power from an electrical grid; and a monitor module that selectively detects a fault event of the electrical grid in response to at least one of (i) an amount of current drawn by the at least one component and (ii) a voltage of power received by the at least one component, wherein in response to detecting the fault event, the control module switches the at least one component from the ON state to a second state, wherein the at least one component consumes less power in the second state than in the ON 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 at least one component back to the ON state. - View Dependent Claims (17, 18, 19, 20)
