• Abstract:

  The analysis of electrical grounding and the preparation of technical reports are fundamental procedures in Electrical Engineering, aimed at guaranteeing the safety and efficiency of electrical installations. This article presents a literature review on this subject, focusing on the Fall of Potential method, addressing theoretical and practical aspects, and the use of the Megabras MTD-20KWe earth meter. The research was carried out by consulting a variety of sources, including scientific articles, professional videos, books, national and international technical standards, with emphasis on ABNT NBR 15749/2009 - Measurement of Grounding Resistance and Potentials on the Ground Surface in Grounding Systems. It was therefore concluded that this is an effective method, but that it must be based on careful visual analysis and has limitations to be observed, such as in the case of densely populated areas and extensive grounding systems, requiring other methods for these analyses that are able to overcome the adversities found in these environments.
