CLAIMS

What is claimed is:

1. A generator grounding module selectively mountable to a support bracket and selectively engageable with a rotor, the generator grounding module comprising:

a plate member movable along a mounting axis to selectively attach the generator grounding module to the support bracket, the plate member movable between a first position and a second position in which the plate member is substantially fixed with respect to the support bracket;

a mounting block movable along the mounting axis with respect to the plate member; a grounding strap coupled to the mounting block and movable between a disengaged position and an engaged position in which the grounding strap contacts the rotor; and

a biasing assembly connected to the plate member and the mounting block and operable to bias the mounting block along the mounting axis toward the plate member, wherein the plate member is fixedly attached to the support bracket when in the second position and the biasing assembly biases the grounding strap into the engaged position.

2. The generator grounding module of claim 1 , wherein the mounting axis is a radial axis of the rotor.

3. The generator grounding module of claim 1, further comprising a mounting arm fixedly attached to the mounting block and defining a first end and a second end spaced apart from the first end, the grounding strap attached to the first end and the second end.

4. The generator grounding module of claim 3, wherein the mounting arm includes a first arm that defines the first end and a separate second arm that defines the second end.

5. The generator grounding module of claim 3, further comprising a second grounding strap attached to the first end and the second end and spaced a non-zero distance in the mounting direction from the grounding strap.

6. The generator grounding module of claim 5, further comprising a sensor positioned to generate a signal in response to a failure of the grounding strap and the second grounding strap.

7. The generator grounding module of claim 1 , wherein the biasing assembly includes a biasing member that applies a constant biasing force to the mounting block as the mounting block moves between the disengaged position and the engaged position.

8. The generator grounding module of claim 7, wherein the biasing member includes a coiled metal band having a coiled end attached to the plate member and a free end attached to the mounting block.

9. The generator grounding module of claim 1 , further comprising a handle coupled to the plate member and operable to move the plate member along the mounting axis between the first position and the second position.

10. The generator grounding module of claim 9, wherein the handle includes a locking member selectively engageable with the support bracket to lock the plate member in the second position.

11. The generator grounding module of claim 1 , further comprising a sensor positioned to detect displacement of the mounting block toward the plate member when the plate member is in the first position.

12. The generator grounding module of claim 11, wherein the sensor includes a switch positioned to be activated in response to a failure of the grounding strap.

13. The generator grounding module of claim 1, wherein the grounding strap is formed from a braided metal.

14. A generator grounding module selectively mountable to a support bracket and selectively engageable with a rotor, the generator grounding module comprising:

a mounting block movable along a mounting axis with respect to the support bracket; a first grounding strap;

a second grounding strap;

an attachment assembly operable to connect the first grounding strap and the second grounding strap to the mounting block, the mounting block movable between a disengaged position and an engaged position in which the first grounding strap contacts the rotor and the second grounding strap is spaced apart from the rotor; and

a biasing assembly connected to the support bracket and the mounting block and operable to bias the mounting block along the mounting axis toward the rotor, wherein the biasing assembly biases the first grounding strap into the engaged position.

15. The generator grounding module of claim 14, wherein the mounting axis is a radial axis of the rotor.

16. The generator grounding module of claim 14, further comprising a mounting arm fixedly attached to the mounting block and defining a first end and a second end spaced apart from the first end, the first grounding strap and the second grounding strap attached to the first end and the second end and spaced a non-zero distance in the mounting direction from the first grounding strap.

17. The generator grounding module of claim 16, wherein the mounting arm includes a first arm that defines the first end and a separate second arm that defines the second end.

18. The generator grounding module of claim 14, further comprising a sensor positioned to generate a signal in response to a failure of the first grounding strap and the second grounding strap.

19. The generator grounding module of claim 14, wherein the biasing assembly includes a biasing member that applies a constant biasing force to the mounting block as the mounting block moves between the disengaged position and the engaged position.

20. The generator grounding module of claim 19, wherein the biasing member includes a coiled metal band having a coil end attached to the plate member and a free end attached to the mounting block.

21. The generator grounding module of claim 14, further comprising a plate member movable along the mounting axis between a first position and a second position in which the plate member is substantially fixed with respect to the support bracket.

22. The generator grounding module of claim 21, further comprising a handle coupled to the plate member and operable to move the plate member along the mounting axis between the first position and the second position.

23. The generator grounding module of claim 22, wherein the handle includes a locking member selectively engageable with the support bracket to lock the plate member in the second position.

24. The generator grounding module of claim 21, further comprising a sensor positioned to detect displacement of the mounting block toward the plate member when the plate member is in the first position.

25. The generator grounding module of claim 24, wherein the sensor includes a switch positioned to be activated in response to a failure of the grounding strap.
