Abstract

A system for diagnosing integrity of an electrical conductor-carrying system can include an electrical conductor-carrying network having a number of electrical conductor-carrying devices mechanically coupled to each other, where at least a portion of the electrical conductor-carrying network is made of electrically conductive material. The system can also include a number of sensor modules coupled to the electrical conductor-carrying network. The system can further include a control unit communicably coupled to the sensor modules. The sensor modules can measure at least one impedance in the electrical conductor-carrying devices of the electrical conductor-carrying network.

First claim

What is claimed is:

1. A system for diagnosing ground integrity of a pipe network, the system comprising:
the pipe network comprising a plurality of pipes mechanically coupled to each other, wherein the plurality of pipes is made of electrically conductive material;
a plurality of sensor modules coupled to and distributed throughout the pipe network; and
a control unit communicably coupled to the plurality of sensor modules,
wherein each of the plurality of sensor modules takes measurements of at least one impedance in the plurality of pipes at a location among a plurality of locations in the pipe network,
wherein the control unit uses the measurements made by the plurality of sensor modules at the plurality of locations to identify a target zone within the pipe network in which the ground integrity is degraded,
wherein the measurements of the at least one impedance indicate the ground integrity of a pipe relative to other pipes, and wherein the measurements of the at least one impedance made by the plurality of sensor modules are made independent of how power is provided to the plurality of sensor modules to perform such measurements and independent of content disposed within the pipe network.

2. The system of claim 1 , further comprising:
at least one electrical cable disposed within the plurality of pipes, wherein the plurality of sensor modules operate based on power flowing through the at least one electrical cable.

3. The system of claim 2 , wherein a first sensor module of the plurality of sensor modules comprises an inductor disposed around the at least one electrical cable, wherein the inductor provides the power to the first sensor module.

4. The system of claim 3 , wherein the pipe network comprises a removable cover, wherein the first sensor module is accessible when the removable cover is removed from the pipe network.

5. The system of claim 4 , wherein the first sensor module replaces the removable cover.

6. The system of claim 4 , wherein the removable cover is part of an existing enclosure of the pipe network.

7. The system of claim 1 , wherein at least one of the plurality of sensor modules are communicably coupled to the control unit using wireless technology.

8. The system of claim 1 , wherein the plurality of sensor modules take the measurements of the at least one impedance in the plurality of pipes over a period of time.

9. The system of claim 8 , wherein the plurality of measurements indicate corrosion in the target zone of the pipe network, wherein the target zone is specifically identified within the pipe network.

10. The system of claim 8 , wherein the plurality of measurements indicate a faulty ground connection in the target zone of the pipe network.

11. The system of claim 1 , wherein at least one of the plurality of sensor modules is self-calibrating.

12. The system of claim 1 , wherein the plurality of sensor modules are movable by a user between the pipe network and another pipe network.

13. The system of claim 1 , wherein the pipe network is located in a hazardous environment.

14. The system of claim 1 , wherein the control unit is communicably coupled to an additional control unit used with another plurality of sensor modules in another pipe network.

15. The system of claim 1 , wherein at least one of the plurality of sensor modules wraps around a pipe of the pipe network.

16. The system of claim 1 , wherein the plurality of pipes is void of non-electrically-conductive material.
