The Basics of Reducing Touch Potential Electrical
Step Potential and Touch Potentials are very important in substations because during ground faults all the ground current returns to the substation transformer (as the substation transformer is grounded). The current that returns through the earth can create a significant voltage gradient along the ground and between ground and conducting objects.... Touch Potential is the difference in voltage between the object touched and the ground point just below the person touching the object when ground currents are flowing.[7] Figure 4.

What is Step & Touch Potential? Definition & Explanation

The step potential is defined as the potential difference between a people’s outstretched feet, normally 1 meter apart, without the person touching any earthed structure....
Touch Potential Contact Voltage An investigation in to Step and Touch Voltages Potentials Created by Incidental Tree-to-Conductor Contacts on overhead distribution lines. Jwgoodfellow@msn com Incidental Tree-Conductor Contacts It is common for 10% of the trees to have made incidental contact with energized distribution conductors prior to scheduled maintence pruning. So called “burners

  • C. Step and touch potential criteria: terms step and touch potential is described earlier in introduction. This is calculated for the determination of safe value of step and touch potential. The calculation is bifurcated in two ways. One is for 50Kg weight operating personnel and another is 70Kg weight. Here the term Cs is the empirical expression for finding the safety criteria. This can be

  • Workers on the ground and on a pole encounter touch potential more than step potential. GROUND GRADIENT Ground Gradient is a term used to describe the electrical field established around the current’s point of entry into the ground from SSG’S. TOUCH POTENTIAL A touch potential is caused when a person creates a current path to ground by touching an energized conductor. Page 1 of 2 .
