  • Patent number: 7761910
    Abstract: A power management architecture for an electrical power distribution system, or portion thereof, is disclosed. The architecture includes multiple intelligent electronic devices (“IED's”) distributed throughout the power distribution system to manage the flow and consumption of power from the system. The IED's are linked via a network to back-end servers. Security mechanisms are further provided which protect and otherwise ensure the authenticity of communications transmitted via the network in furtherance of the management of the distribution and consumption of electrical power by the architecture. In particular, public key cryptography is employed to identify components of the architecture and provide for secure communication of power management data among those components. Further, certificates and certificate authorities are utilized to further ensure integrity of the security mechanism.

  • Patent number: 7265533
    Abstract: Systems and methods for monitoring power in a conductor. A flex circuit may include multiple layers including a voltage sensing layer, a coil layer, and a ground layer. The coil layer includes traces that form a coil structure around a conductor when the flex circuit is wrapped around the conductor. The coil layer generates a voltage that may be integrated to determine a current in the conductor. When the flex circuit is wrapped around the conductor, the voltage sensing layer is closest to the conductor. The voltage sensing layer forms a capacitor with the conductor. Using an adjustable capacitive voltage divider, the voltage of the conductor may be determined from a voltage signal received from the voltage sensing layer.

  • Patent number: 7191076
    Abstract: An intelligent electronic device (IED) includes a base module having a power monitoring circuit operative to monitor a parameter of a portion of a power distribution system and generate an analog signal representative thereof. The base module also includes a processor coupled with the power monitoring circuit, the processor having an analog to digital converter operative to convert the analog signal to a digital signal representative thereof. The processor operates to implement a first power management functionality and generate first power management data. At least one of a display and a communications interface couple with the processor and communicate the first power management data external to the IED. A first interface couples with the processor and the communications interface. The first interface operates to receive a first external function module.
