The following paper provides a method to estimate current distribution of cathodic protection systems using a simple electrostatic model in a common spreadsheet. The model is intended to allow for a rapid analysis of current distribution, polarization, and circuit resistance without having to resort to more complex BEM-type tools. The model is based on the representation of anodes and cathodes by simple charges.
