Abstract

The invention includes a method for transferring a power load between adjacent electrical conductors using a temporary transfer bus, and the transfer bus apparatus itself, wherein the transfer bus includes first and second conductive sections rigidly mounted to and separated by a rigid bus insulator, and a selectively operable transfer bus closing device adapted to selectively electrically connect the first and second conductive sections to each other, the method including suspending the first and second conductive sections from the adjacent conductors, whether directly or using suspension insulators, electrically connecting the conductive sections to the conductors, and closing the transfer bus closing device.

First claim

c. providing a selectively operable transfer bus closing device adapted to selectively electrically connect the first and second conductive sections to each other.

2. The method of claim 1 further comprising electrically connecting the conductive sections to the conductors and closing the closing device across the bus insulator so as to transfer the power load between the first and second conductors.

3. The method of claim 1 further comprising mounting first and second suspension insulators between the first and second conductors and the first and second conductive sections respectively and mounting distal ends of the first and second conductive sections to, respectively, lower ends of the first and second suspension insulators, electrically connecting the distal ends to the first and second conductors.

4. The method of claim 1 wherein said transfer bus closing device includes an elongate conductive member, mounted at opposite ends thereof to the first and second conductive sections.

5. The method of claim 2 wherein the transfer bus closing device is chosen from the group including electrically conductive metallic member, a bus jumper cable.

6. The method of claim 3 further comprising providing at least first and second jumper cables and electrically connecting the distal ends of the first and second conductive sections to, respectively, the first and second conductors, further comprising electrically connecting the distal end of the first conductive section to the first conductor using the first jumper cable, and electrically connecting the distal end of the second conductive section to the second conductor using the second jumper cable.

7. The method of claim 6 wherein said first and second jumper cables are each a pair of jumper cables.

8. The method of claim 7 wherein each said pair of jumper cables has upper and lower ends, and wherein the lower ends are attached to the distal ends of the respective first and second conductive sections and wherein the upper ends are electrically connected to the respective first and second conductors, and wherein the upper ends of each pair of jumper cables are separated along the respective first or second conductor to stabilize the transfer bus suspended below the first and second conductors.
