Touch Potential
Touch Potential is the voltage difference between a grounded metallic object and the feet of a person touching that object during a fault condition.
Suppose a person is standing on the ground and touches a metallic frame that is grounded.…

Surface layer Derating Factor
The Surface Layer Derating Factor is a correction factor applied to account for the presence of a surface layer (like gravel, crushed rock, or asphalt) on the ground surface, which affects the touch and step voltages in an earthing…

 In power systems, transmission lines have inductance and capacitance. These are energy-storing elements that store energy during normal operation. Whenever a short circuit occurs, the stored energy in these inductive and capacitive elements is released linearly…
