SAN-EARTH vs. Bare Copper Wire – Resistance

Test Site Soil Conditions

Depth 0.2 m 1.72 m 4.3 m 6.88 m 20 m
Resistivity at indicated depth 306 Ω-m 382 Ω-m 186 Ω-m 161 Ω-m 47 Ω-m
Ave. resistivity to indicated depth 306 Ω-m 372 Ω-m 232 Ω-m 332 Ω-m 237 Ω-m

  • SAN-EARTH electrode resistance is 60-70% lower than bare copper counterpoise wire.
  • Installation costs are similar
  • Resistance of the five meter SAN- EARTH electrode is the same as the twenty-meter long bare copper wire
  • Ideal contact with the surrounding soil is achieved because SAN-EARTH conforms to the shape of the trench.
  • The effective surface area of the SAN-EARTH grounding electrode is about 25 times larger than the counterpoise wire.
