Abstract:
A portable electrical energy power node (100) is provided. The power node includes first and second input power terminals (101, 102) and first and second output power terminals (107, 108). The input power terminals are adapted for receiving a source of electrical power and the output terminals are adopted for connecting to a load. A first power line (103) connects the first input terminal to the first output terminal, a second power line (104) connects the second input terminal to the input side of a circuit interrupter (105) and a third power line connects the output side of the circuit interrupter to the second output terminal. The circuit interrupter selectively interrupts the connection between the second input terminal and the second output terminal in accordance with AFCI/GFCI and voltage/current sensors (301, 302) and a control unit (CPU, 315).

Abstract:
A method and apparatus for detecting faults in an electrical circuit (106), such as an overload fault, a ground fault and an arc fault, and for monitoring and controlling electrical energy consumption in the electrical circuit is provided. The monitoring device includes a sensor (109) coupled to the electrical circuit for producing an electrical fault signal when a fault is detected in the circuit, a signal processing unit (110) coupled to the fault sensor for improving the signal to noise ratio of the fault signal, a fault trigger condition register (114) for storing at least one response action to be taken by the monitoring device when the fault condition is detected and a central processing unit (CPU, 116) coupled to the signal processing unit and to the fault trigger condition register. In response to the fault signal, the CPU causes the monitoring device to take a response action, such as controlling a circuit interrupter (105) to interrupt the flow of current in the electrical circuit.
Abstract:
A circuit breaker system (500) integrated into a package including an input for coupling to an external electrical power source, an output for coupling to an external electrical circuit, and a current path selectively coupling the input and the output. A mechanical circuit breaker mechanism (502) interrupts electrical power flow through the current path in response to a current exceeding a predetermined value. A trip solenoid (503) causes the mechanical circuit breaker mechanism to interrupt electrical power flow through current path in response to a control signal. Voltage and current sensors (506) measure voltage and current values of the electrical power flowing through the current path and a microprocessor (501) selectively generates the control signal in response to the measured voltage and current values, along with and a control profile stored in memory, to energize the solenoid and cause the mechanical circuit breaker mechanism to interrupt the electrical power.

Abstract:
A system for hazard mitigation in a structure including a subsystem coupled to a circuit of an electrical distribution system and set of nodes. The nodes monitor operating conditions of the circuit and generate data in response. A data processing system is operable to process the data generated by the set of nodes and in response identify a trigger representing a condition requiring that an action be taken. The data processing system processes the trigger in accordance with a predetermined policy to initiate an action by the subsystem.
