Excellence 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.
