Inductor-Coupled Insulating Structure for Bond-On Transient Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transient currents generated during the bond-on process with energized electrical equipment pose a risk to the insulating structure, particularly in high voltage AC and DC power systems, as they can cause structural failure due to high amplitude and duration, with no existing systems to counter or deflect these currents.
Innovation Solution
An electrically insulating structure with an inductor operatively coupled to its end is used to suppress transient currents during the bond-on process, inhibiting their propagation through the insulating structure by resisting changes in current.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the worker bonds-on to the energized electrical equipment to achieve common potential, then the worker can safely work on the equipment, but transient currents are generated that can cause insulating structure failure
Solution Approach 1:
An inductor is introduced as an intermediary component between the insulating structure and the bonding connection. The inductor suppresses transient currents generated during the bond-on process, preventing them from propagating through the insulating structure while allowing the bonding operation to proceed for worker safety
Solution Approach 2:
The inductor is pre-installed on the insulating structure before the bonding operation occurs. This beforehand cushioning measure prepares the system to absorb and suppress transient currents before they can cause damage, enabling safe bonding operations without risking insulating structure failure
2Reliability
If an inductor is added to suppress transient currents, then the insulating structure is protected from failure, but the device complexity increases
Solution Approach 1:
The inductor is applied locally at specific critical points on the insulating structure where transient current suppression is most needed, rather than throughout the entire system. This localized application protects the insulating structure while minimizing the overall complexity increase
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The inductor effectively reduces the amplitude and duration of transient currents, preventing insulating structure failure and maintaining its integrity during live-line working on high voltage power systems.
Implementation Method 1
an inductor operatively coupled to the first end of the electrically insulating structure... the at least one inductor suppresses transient currents from the energized electrical equipment to thereby inhibit propagation of the transient currents through the insulating structure

AI summary
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.
