Apparatus and Method for Three-Pole Type Measuring Specific Soil Resistance Measurement for Distribution Grounding

摘要

Disclosed herein is an apparatus and method for measuring a specific soil resistance for distribution grounding by a three-electrode method. The apparatus uses three electrodes to measure a specific soil resistance as well as an earth resistance based on a three-electrode method in specific soil resistance measurement that is the most basic but likely to be overlooked in a practical distribution work.
