Tower-footing-R - All Electron - All about High Voltage systems

Tower Footing Resistance calculator

With this tool tower footing resistance measurement data can be analysed. It accepts input from our ‘Measurement Map App‘. Both, the classic Fall-of-potential (FOP) method and the Oblique method can be selected. It includes the option for a distance correction (slope method according to Tagg for FOP) and estimates the local soil resistance (as seen by the tower).
