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.
