Calculation of Touch Voltage and Ground Current

3-phase systems and 1-phase

Calculation of touch voltage and ground current can be performed on single phase or three-phase systems.

According to the inputs for three-phase system: Line-to-Neutral Volts (Vn), Line 1 Calculated Load (A1), Line 2 Calculated Load (A2), Line 3 Calculated Load (A3), Service Neutral Impedance Z1, and Ground Resistance (3-point method) R, spreadsheet will calculate the following parameters:

  1. Resistance of Each Phase
  2. Resistance of neutral/Ground
  3. Neutral Current and Load
  4. Touch Voltage for Metal part to Earth
  5. Body Resistance and Body Current

For single-phase systems input parameters are: Circuit voltage and ampere, load, ground, electrode and body resistance.
