Abstract

A sensored electrical jumper comprises a conductor having a first end and a second end, the first end including a first connection interface and the second end including a second connection interface, a sensor section including at least one sensor disposed over the conductor between the first and second ends, the sensor section sensing at least one of current and voltage of the conductor, and a sensor output conduit extending from the sensor and oriented substantially perpendicular to the conductor axis to protect at least one sensor output wire from leakage current or other potential electrical damage.

First claim

What is claimed is:

1. A sensored electrical jumper, comprising:
a conductor having a first end and a second end, the first end including a first connection interface and the second end including a second connection interface,
a sensor section including at least one sensor disposed over the conductor between the first and second ends, the sensor sensing at least one of current and voltage of the conductor, wherein the sensor includes a capacitive voltage sensor having an inner shield layer in contact with the conductor, an insulation layer disposed over the inner shield layer, and an electrically isolated outer shield layer disposed over the insulation layer,
a stress control tube having a High K layer disposed over at least a portion of the sensor section, and
a sensor output conduit extending from the sensor and oriented substantially perpendicular to the conductor axis to protect at least one sensor output wire from leakage current or other potential electrical damage.

2. The sensored electrical jumper of claim 1 , wherein the sensor output conduit comprises a conductive flexible conduit having an outer insulation layer.

3. The sensored electrical jumper of claim 2 , wherein the conductive flexible conduit comprises a metallic material.

4. The sensored electrical jumper of claim 1 , wherein the electrically isolated outer shield layer comprises an electrically isolated section of conductive or semiconductive material.

5. The sensored electrical jumper of claim 4 , wherein the electrically isolated section of conductive or semiconductive material forms an electrode of a capacitive voltage sensor.

6. The sensored electrical jumper of claim 1 , wherein each connection interface comprises one of a lug, a stem connector, a separable connector, a splice, and a modular connector.

7. The sensored electrical jumper of claim 1 , wherein the sensor section comprises a current sensor.

8. The sensored electrical jumper of claim 1 , wherein the sensor section further comprises a current sensor.

9. The sensored electrical jumper of claim 8 , wherein current sensor is at least partially concentric to the capacitive voltage sensor.

10. The sensored electrical jumper of claim 1 , further including an outer sleeve comprising a tubular body formed from an anti-tracking insulation material.

11. The sensored electrical jumper of claim 10 , wherein the outer sleeve further includes a plurality of skirts.

12. The sensored electrical jumper of claim 10 , further including one or more current collectors disposed on the outer sleeve to collect leakage current.

13. The sensored electrical jumper of claim 10 , further including a deflector portion formed in the outer sleeve proximate to the sensor output conduit.

14. The sensored electrical jumper of claim 1 having a length less than 25 inches.

15. The sensored electrical jumper of claim 1 , wherein each connection interface comprises one or more separable connectors or a modular connector with two or more ends.

16. The sensored electrical jumper of claim 15 , wherein the sensor section further comprises two or more ends.

17. The sensored electrical jumper of claim 15 disposed in a splice, branch splice, separable splice, separable connector, or separable branched splice.

18. The sensored electrical jumper of claim 1 , wherein the sensor section further comprises a temperature sensor.

19. The sensored electrical jumper of claim 1 , wherein the sensor output conduit comprises a nonconductive flexible conduit having an outer insulation layer.
