Abstract

In accordance with certain embodiments of the present disclosure, a cable fault detection device is described. The device includes a conformal monopole structure and a ground plane structure. The ground plane structure is configured to be generally parallel to the cable longitudinal axis.

Claims

1. A cable fault detection device comprising:

a monopole structure; and

a ground plane structure, wherein the ground plane structure is configured to be generally parallel to the cable longitudinal axis.

2. The device of claim 1, wherein the monopole structure comprises copper.

3. The device of claim 1, wherein the ground plane structure comprises copper.

4. The device of claim 1, wherein the ground plane structure further comprises insulating material.

5. The device of claim 1, wherein the monopole structure is generally cylindrical.

6. The device of claim 1, wherein the monopole structure defines a slit which is configured to allow the monopole structure to fit around the cable.

7. The device of claim 1, wherein the ground plane structure is located more than 1 mm away from the monopole structure.

8. The device of claim 1, further comprising a power source configured to derive power from the cable.

9. The device of claim 8, wherein the power source is an energy scavenging system.

10. A method of cable fault detection comprising:

placing a device around a cable, the device comprising a monopole structure and a ground plane structure, wherein the ground plane structure is configured to be generally parallel to the cable longitudinal axis; and

detecting a cable fault through utilization of the device.

11. The method of claim 10, wherein the monopole structure comprises copper.

12. The method of claim 10, wherein the ground plane structure comprises copper.

13. The method of claim 10, wherein the ground plane structure further comprises insulating material.

14. The method of claim 10, wherein the monopole structure is generally cylindrical.

15. The method of claim 10, wherein the monopole structure defines a slit which is configured to allow the monopole structure to fit around the cable.

16. The method of claim 10, wherein the ground plane structure is located more than 1 mm away from the monopole structure.

17. The method of claim 10, further comprising a power source configured to derive power from the cable.

18. The method of claim 17, wherein the power source is an energy scavenging system.

19. The method of claim 10, further comprising a circuit configured to generate an ultra narrow pulse.
