The ground resistance, the ground potential rise, touches and step voltages are the basic design quantities of the grounding grids.
A good earthing grid has low resistance (with respect to remote earth) to minimize ground potential rise (GPR) and consequently avoid dangerous touch and step voltages.
Beginning with a discussion of electrical power system fundamentals, the work covers topics such as ground potential rise and zone of influence, critical telecommunications circuits in high voltage locations, high voltage protection equipment, level III equipment installation and testing, and personnel safety with high voltage protection equipment.
develops and manufactures equipment designed to protect against damage from lightning ground currents, also known as lightning ground potential rise.
Electrical damage from ground potential rise (GPR) has an estimated cost in the millions of dollars a year, but few field engineers or service managers in the industry are even aware of the phenomenon [4].
However, no surge protective device ever made will protect electronic equipment from a ground potential rise [4, 9].
The program is used to perform soil resistivity measurement interpretations, elevation of ground potential rise and danger point evaluation within any area of interest.
This is the ground potential rise of the primary electrode (i.
When the uphill tower was impacted by a lightning strike, the energy wave, or ground potential rise (GPR), would pass through the downhill site with multiple grounds, causing equipment to rise and fall at various times and inducing damage.
Touch voltages over the grid are a small fraction of tile pipeline/grid ground potential rise.
