Substation Rock Resistivity
Substation Rock Resistivity
(OP)
We are empirically testing substation rock spalls for resistivity and come up with around 10,000 ohm-meters of resistivity. The IEEE80 uses a typical example of 2500 to 3000 ohm-meters for substation rock resistivity. Are we way off base? Our samples are 1-1/2" drain rock.






RE: Substation Rock Resistivity
For dry conditions, the resistivity value is much higher in the order on million (10^6) Ohm.m.
