Define touch potential
WebTouch voltage is defined as the potential difference between the ground potential rise of a ground grid or system and the surface potential at the point where a person could be standing while at the same time having a hand in contact with a ground structure. Touch example: A person has 800 V at his feet, so contact with 1000 V equipment results ... WebTouch Potential. Another important use for electrical bonding is to reduce touch potential, especially in long runs of conductive cable tray. When voltage is applied to a conductor, be it a wire or anything else metallic, …
