Our team conducted a grounding study of the 13.8 kV Substation Area. The process began by providing on-site soil resistivity tests for the 13.8 kV substation area using a Fluke 1625 earth/ground tester to perform 4-Point Wenner soil resistivity method testing. Next, we provided ground resistance testing and evaluation for the existing ground system. This evaluation was performed using the fall-of-potential method or a stakeless clamp-on ground test (where appropriate). An overall ground resistance report was developed and the limitations discussed. A new grounding plan with installation detail drawings for the upgraded ground grid required for new equipment installation was developed along with a grounding study report documenting findings and recommendations.
