Experimental impulse response of grounding grids
2011 7th Asia-Pacific International Conference on Lightning, 2011Experimental tests, consisting in the impression of low amplitude impulsive currents with lightning-patterned waveforms on a real grounding grid, were performed to assess the grid transient response. Simultaneous waves of current and grounding potential rise were measured considering the current impression on different points along the grid electrodes (

Impulse impedance of rectangular grounding grids
IEEE Transactions on Power Delivery, 1992In an earlier work B.R. Gupta and B. Thapar (1980) presented the results of investigations and empirical formulae to evaluate the impulse impedance of square grounding grids. In the present work, the authors extend those investigations to the rectangular grounding grids.

Simplified Analysis of Rectangular Grounding Grids
IEEE Transactions on Power Apparatus and Systems, 1979A simple and rapid method for designing and analyzing regular, multimeshed rectangular grounding grids is presented. The procedure is based on an extension of principles enunciated in IEEE Standard 80 dated June 30, 1976. By this method, using an engineering type pocket calculator, touch potentials can be determined in a few minutes for any given set ...

Effect of grid spacing on the inductance of ground grids
IEEE 1991 International Symposium on Electromagnetic Compatibility, 2002The effect of grid spacing on the inductances of various paths on a printed circuit board (PCB) is investigated numerically. Partial inductances of the various segments of the paths and the ground grid are incorporated into a lumped model which is solved for the currents using the mesh current method.

Optimization of grounding grid's multidesign geometry
2016 IEEE 16th International Conference on Environment and Electrical Engineering (EEEIC), 2016This paper deals with the optimization of grounding grids geometry. The goal is to reduce the amount of material to deploy a grounding grid, while keeping the system security. The touch voltages, step voltages, GPR and ground resistance are parameters of grounding grids and are related to safety aspect.
