System and method utilizing virtual switching for electrical panel metering
View Patent ↗A system and method utilizing virtual switching in an electrical panel meter. The virtual switching enables the meter to be upgraded or downgraded through a switching signal, by activating or deactivating the metering functions that are to be performed in the meter. Accordingly, when the upgrade or downgrade is necessary, the meter does not have to be replaced.

5. The system of claim 1 , wherein the virtual switching unit is provided with hardware operative to selectively active and deactivate the multiple metering functions in response to the single switching signal.
6. The system of claim 1 , wherein the multiple metering functions are selected from the group consisting of measuring voltage, current, vars, frequency, power, watt-hours, vars/hours, demand and harmonics.
7. The system of claim 1 , wherein the single switching signal is transmitted to the at least one electrical metering device via one of the internet, a telephone line, a direct communication line, and wireless transmission.
8. The system of claim 1 , wherein the single switching signal is transmitted to the at least one electrical metering device via TCP/IP.
9. The system of claim 1 , wherein the single switching signal includes a unique code associated with the at least one electrical metering device.
10. The system of claim 9 , wherein the unique code is generated by an encryption algorithm based on a serial number of the at least one electrical metering device.
11. The system of claim 1 , further comprising an input device configured to select the at least two available metering functions, wherein the single switching signal is generated by the at least one electrical metering device based on the selected at least two available metering functions.
12. The system of claim 1 , wherein the service provider is configured to generate the single switching signal in response to a request from the at least one electrical metering device.
13. The system of claim 12 , wherein the at least one electrical metering device further comprises a display configured for presenting a list of available metering functions and an input device configured for enabling or disabling the at least two available metering functions, wherein the request is generated based on the enabled or disabled at least two available metering functions.
14. The system of claim 13 , wherein the input device is a touchscreen or keypad.
15. In an electrical metering system including at least one electrical metering device including a function unit storing multiple electrical metering functions and a virtual switching unit including a plurality of virtual switches, each virtual switch corresponding to each available electrical metering function for selectively activating and deactivating the corresponding electrical metering function and a service provider for configuring the at least one electrical metering device, a method of upgrading the at least one electrical metering device comprising:
presenting a list of available electrical metering functions on a display of the at least one electrical metering device;
enabling or disabling at least two available electrical metering functions from the presented list and sending the enabled at least two available electrical metering functions to the service provider;
generating a single switch signal at the service provider for activating each virtual switch corresponding to each enabled electrical metering function and deactivating each virtual switch corresponding to each disabled electrical metering function; and
receiving the single switch signal by the virtual switching unit of the at least one electrical metering device;
determining which of the at least two available electrical metering functions is enabled or disabled; and
selectively activating each virtual switch corresponding to each enabled electrical metering function and deactivating each virtual switch corresponding to each disabled electrical metering function.
16. The method of claim 15 , further comprising charging a user based on a number of the multiple electrical metering functions that are enabled.
17. The method of claim 15 , wherein the at least one electrical metering device further comprises a display configured for presenting the list and an input device configured for enabling or disabling the at least two available electrical metering functions, wherein the single switch signal is generated in the at least one electrical metering device.
18. The method of claim 15 , further comprising:
storing readings of the multiple electrical metering functions; and
displaying the readings of the multiple electrical metering functions.
19. The method of claim 15 , wherein the single switch signal is transmitted to the at least one electrical metering device via one of the Ethernet and wireless transmission.
20. The method of claim 15 , wherein the single switch signal is transmitted to the at least one electrical metering device via TCP/IP.
21. The method of claim 15 , wherein the multiple electrical metering functions are selected from the group consisting of measuring voltage, current, vars, frequency, power, watt-hours, vars/hours, demand and harmonics.
22. The method of claim 15 , wherein the single switch signal includes a unique code associated with the at least one electrical metering device.
23. The method of claim 22 , wherein the unique code is generated by an encryption algorithm based on a serial number of the at least one electrical metering device.
