Nonuniform Characteristics of a Horizontal Grounding Electrode
IEEE Transactions on Power Delivery, 2007This paper has investigated the nonuniform characteristics of a counterpoise based on the frequency-dependence of R, L, C, and G and propagation parameters identified from measured results of transient voltages and currents on the counterpoise. It becomes clear that the characteristic impedance is significantly length-dependent (i.e non-uniform, at a ...

Calculation of Impulse Grounding Resistance of Extended Grounding Electrode
2013In order to calculate the impulse grounding resistance of extended grounding electrode accurately, this paper introduces a method for computing the impulse grounding resistance based on the spark discharge characteristic of the earth, using a nonlinear differential circuit model. The relation curves of impulse grounding resistance with the current peak

Research of Electromagnetic Flowmeter with Grounding Electrode
Advanced Materials Research, 2013Grounding electrode electromagnetic flowmeter can reduce the loss of the measurement signal,and the conductivity lower medium can be measured if the area of the grounding electrode was increased. However, if the grounding electrode area is increased, the measurement signal will be reduced.

Measurement of chemical ground electrode performance
2012 6th Asia-Pacific Conference on Environmental Electromagnetics (CEEM), 2012We can reduce the grounding resistance of grounding object by reducing the resistivity of the soil, increasing the size of the area of ground, selecting the appropriate shape of the grounding (depth of the vertical ground) and increasing the number of vertical ground, etc. However, when the spot area is limited and soil resistivity is high, traditional

A Comparison of Concrete Encased Grounding Electrodes to Driven Ground Rods
IEEE Transactions on Industry and General Applications, 1970An experimental study was made to compare the efficacy of concrete encased grounding electrodes to that of driven ground rods for grounding residential and small commercial electric services. This study extended over 14 months and included a very wet winter and a dry summer.

Analysis of Grounding Electrode Input Impedance Calculation
2011The paper deals with an assessment of transient impedance of the grounding electrode. The mathematical model is based on the thin wire antenna theory and related Pocklington integro- differential equation in the frequency domain, which is numerically treated via Galerkin-Bubnov variant of indirect Boundary Element Method (GB- IBEM).
