Why is equipotential grounding preferred over other methods?

Equipotential grounding is preferred primarily because it provides maximum worker safety. This method ensures that the potential difference between conductive elements is minimized, thereby reducing the risk of electrical shock to personnel working in proximity to energized equipment or overhead lines. By creating a uniform potential across the grounding system, linemen are less likely to experience dangerous step or touch voltages that can occur when different parts of a system have varying electrical potentials.

In addition to enhancing safety, equipotential grounding helps protect workers by ensuring that any fault current is safely conducted to ground, thereby reducing the chance of an accident. This practice aligns with safety standards and regulations aimed at protecting workers in the electrical industry.

While other options might have their own merits, such as ease of implementation or cost-effectiveness, the primary concern in the lineman's work environment must always be worker safety. Therefore, equipotential grounding stands out as a crucial method in promoting a safe working environment.
