Calculations

Choose the calculation by the result you need. Each authoritative resource controls its equations, units, assumptions, and interpretation.

Anode System Life

Estimate calculated life using the controlled model for the anode type and stated design assumptions.

Current Requirement

Use applicable area and a source-controlled design current density to estimate total required current.

Use a measured shunt voltage and known shunt data to determine current.

Soil Resistivity — Wenner Apparent Resistivity

Convert valid Wenner resistance and equal pin spacing into apparent soil resistivity with explicit units.
