Smart circuit breaker
First Claim
1. A monitoring device for an AC power supply circuit stepped down or downstream from a high age power transmission line, wherein the AC power supply circuit that has a limited capacity for supplying power to one or more electrical loads, monitoring device comprising:
- a sensing circuit configured ynamically determinean available load capacity of the AC power supply circuit;
a reporting circuit configured to report the dynamically determined available load capacity of the AC power supply circuit, wherein the reporting circuit includes an input/output interface for communications with a controller, an existing electrical load, and/or a potential electrical load on the AC power supply circuit; and
a prediction circuit configured to determine the effects of a potential electrical load of the AC power supply circuit on an existing load of the AC power supply circuit, including determining if the effects on the existing load are within a safe margin of operation with respect to one or more of voltage, current, phase and/or frequency of operation.

Abstract
A smart circuit breaker for an AC power supply circuit that has a limited capacity for supplying power to one or more electrical loads. Smart circuit breaker includes a sensing circuit to dynamically determine the available load capacity of the AC power supply circuit. A reporting circuit reports the dynamically available load capacity to a controller, an existing electrical load, and/or a potential electrical load on the AC power supply circuit. The AC power supply circuit, the existing electrical load, and/or the potential electrical load can adjust operations based on the reported availability of load capacity.
