Abstract

A grounding assembly for electronic equipment provides a discharge path for the energy arising from lightning strikes. A conductive strap connects the ground lug of the equipment to a ground plate buried in the earth. The conductive strap has a length, width and thickness, with the width being greater than the thickness. This reduces the inductance of the conductor from the controller to the ground plate, thereby enhancing the ability of the grounding assembly to dissipate energy from lightning strikes.

Claims

1. A grounding assembly providing a discharge path for lightning arrestors protecting electronic equipment, the grounding assembly comprising:

a ground plate providing a discharge path terminus adapted for subterranean installation; and

an electrically conductive strap having a first end and a second end, the first end connected to the ground plate and the second end electrically connectable to the electronic equipment, the conductive strap having a width and thickness, the width being greater than the thickness, wherein the ground plate has a thickness and wherein the thickness of the conductive strap is about the same as the thickness of the ground plate.

2. The grounding assembly of claim 1 wherein the thickness of the conductive strap and of the ground plate is about 0.0625 inches.

3. The grounding assembly of claim 2 wherein the conductive strap is about 0.5 inches wide.

4. The grounding assembly of claim 1 wherein the conductive strap is about 0.5 inches wide.

5. The grounding assembly of claim 1 wherein the conductive strap is made of copper.

6. The grounding assembly of claim 1 wherein the ground plate is made of copper.

7. The grounding assembly of claim 1 wherein the ground plate and conductive strap are formed from a unitary piece of material.

8. The grounding assembly of claim 1 further comprising a ground rod and a wire connecting the ground rod to the electronic equipment.

9. The grounding assembly of claim 1 further comprising a ground bar made of electrically conductive material and having at least one slot formed therein for receiving the conductive strap.

10. The grounding assembly of claim 9 further comprising a ground wire electrically connectable to the electronic equipment, and the ground bar further comprising at least one bore for receiving said ground wire.

11. In a grounding assembly for providing a discharge path for lightning arrestors protecting electronic equipment, the grounding assembly including a ground plate providing a discharge path terminus adapted for subterranean installation, a method of reducing the inductance from the electronic equipment to the ground plate, comprising the step of electrically connecting the electronic equipment to the ground plate with an electrically conductive strap having a first end and a second end, wherein the first end is connected to the ground plate and the second end is connectable to the electronic equipment, the conductive strap further comprising a width and thickness, the width being greater than the thickness and wherein the ground plate has a thickness and the thickness of the conductive strap is the about same as the thickness of the ground plate.

12. The method of claim 11 further comprising the steps of providing a ground bar made of electrically conductive material and having at least one slot and at least one bore formed therein, inserting the conductive strap into the slot, inserting a ground wire into the bore, and electrically connecting the ground wire to the electronic equipment.

13. A grounding assembly providing a discharge path for lightning arrestors protecting electronic equipment, the grounding assembly comprising:

a ground plate providing a discharge path terminus adapted for subterranean installation; and

an electrically conductive strap having a first end and a second end, the first end connected to the ground plate and the second end electrically connectable to the electronic equipment, the conductive strap having a cross sectional shape the inductance of which is less than that of a fully circular cross sectional shape.

14. The grounding assembly of claim 13 wherein the ground plate and the conductive strap each have a thickness and wherein the thickness of the conductive strap is about the same as the thickness of the ground plate.

15. The grounding assembly of claim 14 wherein the thickness of the conductive strap and of the ground plate is about 0.0625 inches.

16. The grounding assembly of claim 15 wherein the conductive strap is about 0.5 inches wide.

17. The grounding assembly of claim 13 wherein the conductive strap is about 0.5 inches wide.
