Abstract

A power monitoring system with multiple sensors for electrical panels providing power through multiple electrical conductors. The power monitoring system preferably includes at least four sensors supported in a fixed spatial relationship on a support. The sensors include openings through which electrical conductors may be extended.

Claims

1. An electrical sensing device comprising:

(a) a first sensor comprising a first sensor body including a first sensor surface and defining a first aperture extending through said first sensor body;

(b) a second sensor comprising a second sensor body attached to said first sensor body, said second sensor body including a second sensor surface and defining a second aperture extending through said second sensor body; and

(c) a third sensor comprising a third sensor body attached to said second sensor body, said third sensor body including a third sensor surface and defining a third aperture extending through said third sensor body;

said first sensor surface, said second sensor surface and said third sensor surface being substantially aligned along a linear axis and said first aperture, said second aperture and said third aperture being spaced in a non-overlapping relationship.

2. The electrical sensing device of claim 1 wherein a central axis of each of said first, said second and said third apertures is arranged substantially normal to said linear axis.

3. The electrical sensing device of claim 1 wherein each of said first, said second and said third sensors includes a toroidal core.

4. The electrical sensing device of claim 1 wherein said first, said second and said third sensors are securable to a surface by securing one of said first, said second and said third sensors to said surface.

5. The electrical sensing device of claim 1 wherein at least one of said first, said second and said third sensors comprises a split toroidal core.

6. The electrical sensing device of claim 1 wherein said first, said second and said third sensors each further comprise a wire wound around a section of a toroidal core, said wires from said first, said second, and said third sensors terminating at a connector secured to one of said first, said second and said third sensor bodies.

7. The electrical sensing device of claim 1 wherein each of said first, said second and said third apertures are further defined by a central axis and said central axes of said first, said second and said third apertures are arranged substantially in a line.

8. The electrical sensing device of claim 1 wherein said second sensor body surface includes a portion overlapped by a portion of said first sensor body surface and another portion overlapped by a portion said third sensor body surface.

9. The electrical sensing device of claim 8 wherein a central axis of each of said first, said second and said third apertures is arranged substantially normal to said linear axis.

10. The electrical sensing device of claim 8 wherein each of said first, said second and said third sensors includes a toroidal core.

11. The electrical sensing device of claim 8 wherein said first, said second and said third sensors are securable to a surface by securing one of said first, said second and said third sensors to said surface.

12. The electrical sensing device of claim 8 wherein said first, said second and said third sensors each further comprise a wire wound around a section of a toroidal core, said wires from said first, said second, and said third sensors terminating at a connector secured to one of said first, said second and said third sensor bodies.

13. The electrical sensing device of claim 8 wherein each of said first, said second and said third apertures are further defined by a central axis and said central axes of said first, said second and said third apertures are arranged substantially in a line.
