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:
