Grounding Studies
“Primary objective is to determine if a ground grid or ground mat design will limit the neutral-to-ground voltages normally present during ground faults to the tolerating values.”
Ground grid and mat studies calculate the voltage differences between the grounding grid and points at the earth surface and evaluate the shock hazard involved.
This Study specifically identifies unsafe areas within a proposed mat / grid and optimizes the grid design while verifying that the design is safe throughout the area(s) in question.
Just a reminder…
- A normal healthy person can feel a current of about 1 milliampere (1mA).
- Currents of approximately 10-25 milliamperes can cause lack of muscular control.
- In most men, 100 mA will cause ventricular fibrillation.
- Higher currents can stop the heart completely or cause severe electrical burns.
