Step Potential

Step potential is the step voltage between the feet of a person standing near an energized grounded object. It is equal to the difference in voltage, given by the voltage distribution curve, between two points at different distances from the electrode. A person could be at risk of injury during a fault simply by standing near the grounding point.

Touch Potential

Touch potential is the touch voltage between the energized object and the feet of a person in contact with the object. It is equal to the difference in voltage between the object and a point some distance...

Remote field operations present the safety organization with a myriad of challenges when it comes to ensuring the safety of the people that you send out to work in the field every day. Without a doubt, this includes the line workers, but it also includes nearly every member of the staff whose duties are performed outside of the controlled confines of your facilities. Certainly, many of the hazards are identifiable and risk mitigation procedures and equipment are deployed, along with your remote crews, in the effort to keep everyone safe and bring them back home at the end of the...
