Many of today's energy metering systems such as residential and commercial electric and gas meters are bulky and not conveniently mounted or integrated with new or existing infrastructure. Conventional diaphragm meters (e.g., such as gas and some electric meters) include many moving parts such as chambers, gears, flag arm assemblies, valves, and other components that necessitate a relatively bulky housing, periodic maintenance, and/or have an undesirable life-span. Further, most current conventional meters are not remotely readable, and don't offer any other functionality beyond usage metering. Moreover, mounting pedestals for self-contained meters are also bulky and costly, and are generally difficult to integrate with adjoining systems.
With the accelerating growth of distributed energy systems and mobile transportation and infrastructure, it would be desirable to provide energy metering systems that can be easily and unobtrusively integrated with existing infrastructure to provide convenient energy delivery, and real time consumption monitoring and transactions. Furthermore, many residential and small commercial customers would benefit from advanced design solid-state meters housing in a smaller footprint that provide various convenience, customization, and safety features such as wireless communication and access, pressure monitoring, seismic detection, automatic methane detection (e.g., for in-house and on-site gas leak detection, electrical malfunction or shorting), automatic safety shut-off valves, remote/turn-on capability, anti-tamper alarms, pre-payment functionalities, and multi-dwelling design with master/slave communications.

In this instance, information such as energy use (kWh and kVARh), operation function such as real time (or substantially real time) voltages and current, and grid awareness such as the physical location of a mobile electric meter can be processed through the cloud resource linked with a utility data management (system utility data management).
Some embodiments can include provisions for phase voltage, current and phase angle in real (or substantially real) time in a full scale, or by designation or during emergency and/or power outage and restoration situations. In some embodiments, computation of kWh consumption and other power metrics can be done by cloud-computing with various communication back-haul options. This embodiment exemplifies a very different philosophy from the more typical “smart meter” philosophy by performing analyses and computations in the cloud instead of at the meter.
In some embodiments, the electric metering system can function as a telecommunication conduit for other services such as internet, video, TV, advertisements, etc. Moreover, in some embodiments, using customer identification information, the electric metering system can function as a telecommunication conduit for services (i.e. internet, video, TV, advertisements, etc.) that are tailored or targeted to the customer's needs, preferences, or geographic location. In some embodiments, the system can generate licensing fees for revenues that can help lower the customer's energy rate. Further, in some embodiments, the system can enable customers to be informed about commercial services (e.g. shopping), public safety (i.e. police, fire, hospital, etc.), and can be used to improve public and personal safety (i.e. in emergency situations, such as accidents, stranded vehicles, etc.) Some embodiments can also include electrical outage and gas/water leakage monitoring and/or call notifications and identifications. Further, some embodiments can function as or couple to telecom hubs that can provide improved bandwidth for field personnel communications and provide mobile telemetry. In some embodiments, the system can provide local, area-wide, and/or global Internet services.
In some further embodiments, the meter can be associated with or coupled to an electric vehicle, and/or an electric charger, and/or battery storage, and/or a photovoltaic system, and/or a circuit breaker, and/or appliances, and/or infrastructure. In the latter example embodiments, a mobile energy meter and remote application can be used to guide customers when and where to plug in either to charge or discharge, and potentially lower operating/maintenance cost of an electric vehicle. In some embodiments, this can enable customers and utilities to better manage EV loads (when charging) and generations (when discharging), and help lower costs of the grid construction, maintenance and operation. Thus, in some embodiments, EVs with embodiments of the mobile meters described herein can support and benefit the electrical grid system, and customers can be provided with real time charging/discharging cost and kWh quantity. Further, in some embodiments, the electric metering system can function to provide vehicle telemetry and/or form part of a self-driving infrastructure. In some embodiments, using a combination of smart poles and/or micro cell sites, the electric metering system relay vehicle telemetry information, and provide remote monitoring of charge/ discharge within an electric vehicle route. Furthermore, because the cloud-based system can be managed and/or coupled to at least one utility data management system, the system can be used to guide customers when and where to plug in either to charge or discharge based on location, charging station status, local and area-wide grid loads, etc., providing real time location based charge/discharge updates, operating with real time data on the grid.

Some embodiments include a training and practical assessment system and method for metering personnel who may be routinely exposed to hazardous voltages with enough energy to create arc flashes, injury personnel and cause property damage. Some embodiments include a portable device that can simulate various electrical metering field conditions. For example, some embodiments include a software driven tester that can electrically model various field conditions for technician assessment and training. In some embodiments, these models can be pre-programmed and sequenced for testing or Ad-hoc models can also be generated. In some embodiments, the system has the necessary communications and allows the simultaneous and independent testing of up to six technicians
In some embodiments of the invention, the training and practical assessment system and method for metering personnel can comprise a system size and weight that can allow transport in one conventionally sized vehicle. In some embodiments of the invention, the main system components can include, but not be limited to, a power supply (marked as 2503) such as an Omicron CMC 356 (from OMICRON electronics Corp. USA). Some further embodiments include a controller (marked as 2502) such as a National Instruments (Austin, Tex.) NI PXIE controller. In some embodiments of the invention, the training and practical assessment system and method for metering personnel can comprise a NI-PXI-8820 2.2 GHZ Celeron® 1020E dual core, and/or NI PXI-2567 64 channel relay driver modules (4), and/or NI PXI-6224 DAQ/DIO, and/or a NI-PXI-6535 high speed digital I/O. Celeron is a trademark of Intel Corporation or its subsidiaries in the United States and elsewhere.
Some embodiments can utilize LabVIEW® software. LabVIEW® is a registered trademark of Tektronix, Inc. Some embodiments include a metering operational assessment tester (“MOAT”) application. Some embodiments include a LabView program “MOAT” that runs on the National Instruments PXI Controller. In some embodiments, this software can be configured to route the requested voltage signal to each meter jaw, and/or notify the trainee when any meter socket is energized, and/or notify the trainee when the problem is ready for evaluation, and/or program the power supply (2503) to generate the appropriate voltages (magnitude and phase). Some embodiments of the system provide physical indication to the trainee on a problem number. Some embodiments run through a pre-programed sequence of problems. Some embodiments only energize active test stations. Some embodiments allow for the simultaneous testing of six technicians while only requiring one trainer (shown as 2505).
Some embodiments include one or more programming test scenarios. In some embodiments, the software can be configured to sequence through programmed steps, progressing at the pace of the trainee 2507, 2509, 2511, 2513, 2515, 2517. Listed below are some of the routines which run to setup the system and present the scenarios to the trainee(s). For example, some embodiments can confirm communications with the power supply 2503. Some embodiments can comprise one or more steps of actions such as select active test stations, select voltage sources, send voltage amplitude and phase information to power supply. Further, some embodiments can comprise one or more actions such as: confirm voltages are within tolerances, energize relays to route signals from power supply to specific meter jaws, and/or notify trainees of socking becoming energized. Some embodiments can comprise one or more actions such as: route selected voltages to all meter jaws, provide indication of question and problem status, query trainee for permission to move on, de-energize all meter jaws, de-energize all test stations, and/or reset for next program.
Some embodiments including parent workstations can comprise two parent workstations that are connected directly to four voltage sources of the power supply 2503. Since each workstation requires two independent voltage sources and the Omicron can generate four separate voltages, this provides the capability to run 2 independent sets of electrical models simultaneously. In some embodiments, the parent workstations can provide voltage and communications connections for the child stations. In some embodiments, the child workstations can comprise four workstations coupled to a parent workstation that can mirror the electricals signals of the parent workstation. In some embodiments, each parent workstation can support up to four child workstations. Finally, in some embodiments, each child station can have the capability to disconnect from the parent for electrical safety if a child is not needed.
Some embodiments include one or more modules that can be used in the workstations. Some embodiments include a display or trainee interface. In some embodiments, this module provides indications to the trainee for socket voltage status, and/or assessment question number, and or socket simulation condition. Further, some embodiments allow the trainee to communicate to the proctor. Some embodiments include an assessment question status and/or an instructor call. And some embodiments include one each of this module on every workstation.
Some embodiments include a socket jaw controller. In some embodiments, this module can control which signal is routed to each meter jaw. In some embodiments, the options can be L1, L2, neutral and ground. In some embodiments, only the parent has this module as the child workstations can mirror their respective parent. In some embodiments, there are nine each of these modules for each parent workstation.
Some embodiments include a voltage selection. In some embodiments, this module can determine which two of the four available voltages are routed to each parent workstation. In some embodiments, this module can control the connection of the neutral and ground connections. In some embodiments, there can be one each installed on each parent workstation.
Some embodiments include a child power control. In some embodiments, this module can independently control the connection of each jaw of the child to the same electrical source as it's respective parent workstation. In some embodiments, this can allow an unneeded child module to be disconnected electrically to eliminate any electrical hazards. In some embodiments, there can be one child power control module for each child meter socket.
In some embodiments, the emergency shutdown system can de-energize all power to every workstation once activated. In some embodiments, each workstation can be equipped with an emergency button which can trigger an emergency shutdown.
