What is a primary benefit of using equipotential zones?

The primary benefit of using equipotential zones lies in minimizing the potential difference across workers. Equipotential zones are designed to maintain the same electrical potential across a given area, thereby reducing the risk of electric shock when workers are operating in electrical environments. By ensuring that there is no significant voltage difference between various conductive surfaces and the ground, workers are less likely to experience harmful currents flowing through their bodies, which significantly enhances safety.

This safety aspect is crucial in high-voltage environments, where even a small potential difference can lead to dangerous or fatal incidents. By establishing these zones, safety measures are significantly improved, allowing for a safer working environment in substations and other electrical facilities.
