What is one of the main functions of personal protective grounds?

Personal protective grounds are primarily used to limit voltage rise during electrical faults. When a fault occurs, such as a line-to-ground fault, the protective grounding equipment ensures that any dangerous voltages do not rise to levels that could pose a risk to personnel working on or near electrical equipment. By grounding the equipment, these systems provide a low-resistance path for fault currents to follow. This helps to stabilize the voltage to the ground in the vicinity, effectively reducing the risk of electric shock or damage that could occur if high voltages were to arise.

The main goal of employing personal protective grounds is to protect safety and mitigate the effects of transient voltages, making it essential for workers who are exposed to potential electrical hazards.
