Abstract

Bypass detection modules associated with a device are provided. The bypass detection module is configured to determine if one of more switches have been opened to remove service from a customer; monitor electrical characteristic associated with both a line side of the device and a load side of the device responsive to determining that one of more of the one or more switches have been opened to remove service from the customer; and determine a state of the device based on the monitored electrical characteristics.

First claim

What is claimed is:

1. A bypass detection module associated with a device, the bypass detection module being configured to:
determine if one or more switches have been opened to remove service from a customer;
monitor electrical characteristic associated with both a line side of the device and a load side of the device responsive to determining that one or more of the one or more switches have been opened to remove service from the customer,
wherein the monitored electric characteristics are voltages, and wherein the bypass detection module is further configured to monitor voltages associated with both the line side of the device (VLine) and the load side of the device (VLoad) responsive to determining that one or more of the one or more switches have been opened to remove service from the customer; and
determine a state of the device based on the monitored voltages, wherein the bypass detection module is further configured to provide an indication of an unlawful bypass as the state of the device if it has been determined that one of or more of the one or more switches have been opened to remove service from the customer and the VLine is substantially equal to the VLoad over a plurality of cycles.

2. The bypass detection module of claim 1 , wherein substantially equal comprises the VLine and the VLoad being within twenty percent of one another.

3. The bypass detection module of claim 1 , wherein the plurality of cycles comprises at least four cycles.

4. The bypass detection module of claim 1 , wherein the device comprises an electric meter.

5. A meter comprising:
a bypass detection module associated with the meter, the bypass detection module being configured to:
determine if one or more switches have been opened to remove service from a customer;
monitor electrical characteristics associated with both a line side of the meter and a load side of the meter responsive to determining that one or more of the one or more switches have been opened to remove service from the customer, wherein the monitored electric characteristics are voltages and wherein the bypass detection module is further configured to monitor voltages associated with both the line side of the meter (VLine) and a load side of the meter (VLoad) responsive to determining that one or more of the one or more switches have been opened to remove service from the customer; and
determine a state of the meter based on the monitored voltages,
wherein the bypass detection module is further configured to provide an indication of an unlawful bypass as the state of the meter if it has been determined that one or more of the one or more switches have been opened to remove service from the customer and the VLine is substantially equal to the VLoad over a plurality of cycles.

6. The meter of claim 5 , wherein substantially equal comprises a line side voltage and a load side voltage being within twenty percent of one another.

7. The meter of claim 5 , wherein the plurality of cycles comprises at least four cycles.

8. A method for detecting a bypass of a device, the method comprising:
determining if one or more switches have been opened to remove service from a customer;
monitoring electrical characteristics associated with both a line side of the device and a load side of the device responsive to determining that one or more of the one or more switches have been opened to remove service from the customer, wherein the monitored electric characteristics are voltages and wherein the method further comprises monitoring voltages associated with both the line side of the device (VLine) and the load side of the device (VLoad) responsive to determining that one or more of the one or more switches have been opened to remove service from the customer; and
determining a state of the device based on the monitored voltages,
wherein the method further comprises providing an indication of an unlawful bypass as the state of the device if it has been determined that one or more of the one or more switches have been opened to remove service from the customer and the VLine is substantially equal to the VLoad over a plurality of cycles; and
wherein at least one of the determining if one or more of the one or more switches have been opened, monitoring and determining a state of the device are performed by at least one processor.

9. The method of claim 8 , wherein substantially equal comprises a line side voltage and a load side voltage being within twenty percent of one another.

10. The method of claim 8 , wherein the plurality of cycles comprises at least four cycles.

11. The method of claim 8 , wherein the device comprises an electric meter.
