An integrated metering device allows a resource provider to control the output of a distributed generation device onto a resource distribution network or grid. The integrated metering device may include a communications module, a metrology module, an inverter and regulator device, and a transfer switch. A resource provider may communicate with the integrated metering device via the communications module and may control the inverter and regulator device or the transfer switch. The metrology module may monitor the energy provided by the distributed generation device to the grid and may send information about the generated energy to the resource provider via the communications module.

Utility meter for use with distributed generation device

A utility meter includes a meter housing that supports at least one current coil, a temperature sensor, and a processing circuit coupled to both. The current coil can be coupled to receive heat energy from a meter socket. The temperature sensor disposed generates a sensor signal based on a temperature within the meter housing. The processing circuit obtains the sensor signal and generates meter temperature information based at least in part thereon. The processing circuit also obtains a first predetermined threshold based on at least one of time of day information and date information. The processing circuit also determines whether an abnormal condition exists by comparing the meter temperature information to a value based on the first predetermined threshold, and generates an output signal to a memory, display or communication circuit responsive to determining that the abnormal condition exists.

A method of controllably disconnecting a utility power service from a load includes generating in a metrology circuit of a meter metering information regarding electrical power provided to the load from the utility power service. The meter includes a service switch having a controller to controllably interrupt a connection between the utility power service and the load. The method also includes connecting an energy storage device to the controller responsive to a service disconnect command. The method further includes connecting at least a portion of the metrology circuit to the energy storage device and disconnecting a meter power supply from the portion of the metrology circuit responsive to a power interruption detection signal.

Power management arrangement and method in a utility meter

An arrangement for controllably disconnecting a utility power service from a load includes a utility meter housing, a service switch, an energy storage device and a control circuit. The utility meter housing includes metrology circuitry configured to generate metering information regarding electrical power provided to the load. The service switch is configured to controllably interrupt a connection between the utility power service and the load, and has a controller. The control circuit is configured to cause the energy storage device to be connected to the controller responsive to a service disconnect command. The control circuit is further configured to cause a portion of the metrology circuit to be connected to the energy storage device and the meter power supply to be disconnected from the portion of the metrology circuit responsive to a power interruption detection signal.

A utility meter comprises a measurement circuit configured to measure consumption, a remote communications port, a local communications port, and a meter communications indicator. The meter communications indicator is configured to provide an indication that the meter is communicating with a remote device external to the meter over the remote communications port. The meter communications indicator is also configured to provide an indication that the meter is communicating with a local device external to the meter over the local communications port. The indication that communications are occurring over the local communications port is different from the indication that communications are occurring over the remote communications port. In at least one embodiment, the communications indicator is configured to provide an indication that communications are occurring simultaneously over the remote communications port and the local communications port.
