What is often the weak link in a running ground?

The interface between the grounding wheel and cable attachment point is often considered the weak link in a running ground. This point is crucial because it is where the mechanical and electrical connection occurs between different components of the grounding system. If this interface is not secure or properly designed, it can lead to increased resistance, hindering the effective transfer of fault currents to the ground. This can result in higher voltage levels at the attachment point during a fault, which can compromise system safety and performance.

Ensuring a solid connection at this interface is vital for optimal grounding performance. This includes considerations such as proper torque on connectors, compatibility of materials to prevent corrosion, and correct physical placement of the grounding wheel. A poor connection can significantly degrade the overall effectiveness of the grounding system, making this interface a critical focus area in grounding system design and maintenance.
