6.2 Single Point Grounding System, Auxiliary Measurement

For single point grounding systems where direct clamp measurement of the lead wire is not feasible, auxiliary methods can be used. The two-point method is illustrated below:

Image 6.2: Diagram showing the two-point method for auxiliary grounding resistance measurement. It depicts a grounding rod (RA) connected to a single point, with a wire extending to a natural grounding point (e.g., water pipe, buried metal) for measurement.

ఈ పద్ధతిని ఉపయోగించడానికి:

• Identify a natural grounding point with a low resistance value near the grounding point to be measured. Examples include a water pipe, fire hydrant, or other deeply buried metal structure.
• Connect a wire from the point to be measured to this auxiliary grounding point.
• Clamp the ETCR2100A+ around the connecting wire to perform the measurement.
