Abstract

A system and method using at least one inductor operatively coupled to an electrically insulating structure suppresses transient currents generated during a bond-on process by a human worker with energized electrical equipment so as to inhibit passage of the transient currents through the electrically insulating structure operatively coupled to the energized electrical equipment.

Claims (20)

1. A system for inhibiting propagation of transient currents, generated during a bond-on process through an insulated boom section, wherein the insulated boom section is used to position a human worker, located on an aerial platform connected to a first end of the insulated boom section, adjacent energized electrical equipment, during the bond-on process, so as to enable the human worker to bond onto the energized electrical equipment through a bonding wand the system comprising:

at least one inductor adapted to be operatively coupled to the first end of the insulated boom section adjacent the aerial lift platform; and

whereby, during the bond-on, when the first end of the insulated boom section and the human worker are positioned adjacent the energized electrical equipment and human worker is bonding onto the energized electrical equipment through the bonding wand for achieving a common potential with the energized electrical equipment, an inductance of the at least one inductor suppresses the transient currents generated during the bond-on process to thereby inhibit propagation of the transient currents through the insulated boom section.

2. The system of claim 1 , wherein the at least one inductor is an air core inductor.

3. The system of claim 1 , wherein the at least one inductor is a flat conductor.

4. The system of claim 1 , wherein the energized electrical equipment is an energized DC electrical power line having a voltage between 10,000 volts to 600,000 volts, inclusive.

5. The system of claim 4 , wherein when the energized DC electrical power line has a voltage between 200,000 volts to 500,000 volts, the inductance of the at least one inductor is at least 100 Microhenries.

6. A method using the system of claim 1 for inhibiting propagation of transient currents, generated during a bond-on process, though an insulated boom section, wherein the insulated boom section is used to position a human worker, located on aerial platform connected to a first end of bond-on process sa as to enable the human worker to bond onto the energized electrical equipment through a bonding wand, the method comprising:

operatively coupling the at least one inductor to the first end of the insulated boom section adjacent the aerial lift platform;

positioning the first end of the insulted boom section and the human worker adjacent the energized electrical equipment;

bonding the human worker onto the energized electrical equipment through the bonding wand; and

suppressing the transient currents, generated during the bond-on process using the at least one inductor to thereby inhibit propagation of the transient currents through the insulated boom section.

7. The system of claim 6 , wherein the insulated boom section houses at least one operating component which is operatively coupled to the aerial lift platform, and wherein the at least one inductor is placed in series with the at least one operating component at the first end of the insulated boom section.

8. The system of claim 7 , wherein the operating component is selected from a group comprising a hydraulic line, a leveling rod or a fiber optic cable.

9. The system of claim 6 , wherein the insulated boom section houses a plurality of operating components which are connected together at a connection point, and wherein the at least one inductor is placed in series with the connection point, between the connection point and the aerial lift platform at the first end of the insulated boom section.

10. The system of claim 6 , wherein the at least one inductor is laminated onto an outer surface of the insulated boom section at the first end.

11. The method of claim 6 , further comprising attaching an electrical link between the energized electrical equipment and the aerial lift platform after the bond-on to the energized electrical equipment.

12. The method of claim 6 , wherein the insulated boom section houses at least one operating component which is operatively coupled to the aerial lift platform, and wherein the operatively coupling step further comprises placing the at least one inductor in series with the at least one operating component at the first end of the insulated boom section.

13. The method of claim 6 , wherein the insulated boom section houses a plurality of operating components which are connected together at a connection point, and wherein the operatively coupling step further comprises placing the at least one inductor in series with the connection point connection point, between the connection point and the aerial lift platform at the first end of the insulated boom section.

14. The method of claim 6 , further comprising laminating the at least one inductor onto an outer surface of the insulated boom section at the first end.
