Abstract: The analysis of electrical grounding and the preparation of technical reports are fundamental procedures in Electrical Engineering, aiming to guarantee the safety and efficiency of electrical installations. This article presents a literature review on this topic focusing on the Potential Drop method, covering theoretical and practical aspects, and the use of the Megabras MTD-20KWe grounding resistance tester. The research was carried out through consultations in a variety of sources, including scientific articles, professional videos, books, national and international technical standards, highlighting the standards ABNT NBR 15749/2009 – Measurement of Grounding Resistance and Potentials on the Soil Surface in Grounding Systems. It was concluded, therefore, that this is an effective method, but that it must be based on careful visual analyzes and has limitations to be observed, as in the case of densely populated areas and extensive grounding systems, making it necessary, for these analyses, other methods capable of overcoming the adversities found in these environments.
