Temporary Conductor Load Transfer for Power Line Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for repairing or re-conductoring energized conductors on power lines are inefficient as they require frequent equipment changes and pose safety hazards due to the need for continuous energization, limiting the ability to maintain or replace conductors without disrupting power supply.
Innovation Solution
A method and apparatus that utilize reusable temporary conductors, where the temporary conductors are energized and de-energized in sequence with the existing conductors to transfer loads, allowing for maintenance without transposing the positions of the energized conductors, enabling efficient re-conductoring across sections without continuous energization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional methods are used for repairing energized conductors, then continuous power supply is maintained, but frequent equipment changes and safety hazards occur
Solution Approach 1:
The patent introduces temporary conductors as intermediary elements that are strung alongside the existing energized conductors. These temporary conductors serve as a mediator to carry the electrical load while the original conductors are being repaired or replaced, eliminating the need to interrupt power supply and avoiding frequent equipment changes.
Solution Approach 2:
The temporary conductors are installed and positioned alongside the existing conductors before any repair work begins. This preliminary action allows the system to be prepared in advance, so that when repair is needed, the temporary conductors are already in place to immediately take over the load without requiring equipment changes during the repair process.
2Productivity
If temporary conductors are used to transfer loads, then maintenance can occur without disrupting power supply, but additional equipment is required
Solution Approach 1:
The temporary conductors are designed to be temporary installations that are discarded after serving their purpose during conductor maintenance. Once the original conductors are repaired or replaced and brought back into service, the temporary conductors are removed and can be recovered for storage or future use, eliminating the need for permanent additional equipment.
Solution Approach 2:
The conductor system is segmented into original conductors and temporary conductors that operate independently. This segmentation allows the temporary conductors to be used only when needed for maintenance operations, reducing overall system complexity while enabling high-productivity maintenance without power disruption.
3Ease of operation
If conductors are de-energized for maintenance, then repair work can be performed safely, but power supply is disrupted
Solution Approach 1:
The temporary conductors act as an intermediary power transmission path that takes over the electrical load when the original conductors are de-energized for maintenance. This mediator system ensures continuous power supply to the load while allowing safe repair work on the original conductors without disruption to the electrical service.
Solution Approach 2:
The system dynamically switches between original conductors and temporary conductors based on maintenance needs. During normal operation, the original conductors carry the load; during maintenance, the temporary conductors take over. This dynamic flexibility allows both safe maintenance operations and continuous power supply to be achieved.

AI summary
A method of using a temporary conductor as a re-usable tool in maintaining, repairing or re-conductoring at least one energized phase, includes stringing the temporary conductor between support structures at either end of a first section, then energizing the said temporary conductor by bringing the temporary conductor to the voltage potential of the phase and electrically paralleling the temporary conductor with the energized phase, de-energizing and then maintaining, repairing or reconductoring the de-energized energized phase, re-energizing and electrically paralleling said energized phase, de-energizing and removing the temporary conductor for later re-use as the re-usable tool in a second section of the energized phase.
