The most common method is performed using a calibrated grounding measuring device (ground megger). <strong>It is the three-point (falling potential) method.<\/strong>. The measurement gives the grounding resistance in ohms.<\/p><\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">Grounding is the invisible but most critical component of electrical safety. In the event of a fault, it safely conducts leakage current to the ground, protecting people from electric shock and preserving equipment from damage.
