  • Publication number: 20110012587
    Abstract: A clamp-on multimeter measures alternating current flow in an electrical conductor. The multimeter includes a display, a housing including the display, a first sensor, a second sensor, a processor and an integrator. The first sensor has a magnetizable material core and inductively senses the alternating current. The first sensor includes a first clamp portion fixed to the housing and a second clamp portion pivotally coupled to the first clamp portion. The second sensor includes a Rogowski coil that has a non-magnetic core and inductively senses the alternating current. The processor receives an input signal in a first voltage range and sends an output signal to the digital display. The integrator scales a signal from the second sensor in a second voltage range to the first voltage range. The housing includes the processor, the integrator, and a selector configured to select the input signal to the processor from one of the first sensor and the integrator.

  • Patent number: 7590499
    Abstract: Aspects of the invention provide apparatuses, methods, and systems that support measuring and conveying energy consumption by an electrical device. An apparatus includes an energy sensor that measures an incremental energy value consumed by an electrical device. Apparatus obtains the incremental energy value, accumulates an energy usage measurement in accordance with the incremental energy value, provides requested information about energy consumption of the electrical device in response to a request from a network controller, and adjusts the energy usage measurement in accordance with the requested information. The total energy consumption may be partitioned into at least one energy component, in which the at least one energy component corresponds to the energy consumption of the electrical device during an associated time interval. A network controller may use the energy consumption information to determine a new set temperature for a thermostat unit that instructs the device control logic.
