DOWNLOAD EBOOKWith the increasing shortage of land in urban and suburban areas, transmission rights-of-way are becoming more crowded by subdivision development and joint use. The public is more frequently exposed to the possibility of ground fault potential rise effects from high voltage overhead transmission lines and underground cables passing close to and sometimes across private lots. A number of scenarios for hazardous conditions and methods that can be applied to analyze them are presented. Safety criteria and touch and step potential analysis including network analysis for varied scenarios are discussed. Scenarios examined include overhead transmission lines, ground electrodes, sky-wire installation, underground transmission lines, sheath cross-bonding, and manhole grounding.
