EARTH IMPEDANCE TEST Directly refers to voltage rises in systems under fault. “Off frequency” current is injected to the earth grid. Use of independent cable and stake or out of service overhead line. Linear Method C Current stake) =5D. Reference potential P≈0.62C Choose a current frequency near the line frequency. Select that current with the Freq. Selective Multimeter. The impedance is automatically calculated. For more accurate results use frequency interpolation. Other arrays (perpendicular, angle, etc.)
STEP & TOUCH VOLTAGES Under fault conditions, currents flowing through the earth grid cause voltage gradients. Touch voltages: between hand accessible points and the feet. Step Voltages: Between feet while walking. Electrocution risk. Use same injection circuit as earth impedance. Set the freq. selective multimeter to 1kΩ internal resistance. Circular metal discs of 8cm radius simulate feet. Measure different points searching for high risk areas.
SURFACE POTENTIAL DISTRIBUTION Detailed state of the grounding system. Voltages measured at equidistant points over the grid. Graphs easily generated. Same injection circuit used to calculate impedance. Imaginary grid is laid over the substation With the Freq. selective multimeter measure voltage difference between injection and equidistant points. Good performance grounding should be flat, slight elevations at both ends.
SOIL RESISTIVITY Important parameter for earth system design. Impedance influenced by the soil resistivity. Wenner array simplest method. Inject current through the current stakes. Frequency selective multimeter calculates the resistance. Resistivity can be calculated using the formula that suits this array:
