Earth Resistance Testing as per IS 3043 with Report
Soil resistivity is a measure of how much the soil resists or conducts electric
current. It is a critical factor in design of systems that rely on passing
current through the Earth's surface. An understanding of the soil resistivity
and how it varies with depth in the soil is necessary to design the grounding
system in an electrical substation, or for lightning conductors.
It is needed for design of grounding (earthing) electrodes for substations and High-voltage
direct current transmission systems. It was formerly important in earth-return
telegraphy. It can also be a useful measure in agriculture as a proxy measurement
for moisture content.
