A Method for Calculating Grounding Resistance of Reinforced Concrete Foundation Grounding Systems

open access: yesEnergies, 2022
Tower foundations have been used as grounding electrodes to reduce the area of the grounding devices. However, it is difficult to calculate the grounding resistance due to the complex structure of the reinforced concrete foundation.

A versatile all-channel stimulator for electrode arrays, with real-time control [PDF]

open access: yes, 2004
Over the last few decades, technology to record through ever increasing numbers of electrodes has become available to electrophysiologists. For the study of distributed neural processing, however, the ability to stimulate through equal numbers of ...

Seasonal Influences on the Impulse Characteristics of Grounding Systems for Tropical Countries

open access: yesEnergies, 2019
One of the most important parameters of the performance of grounding systems is the soil resistivity. As generally known, the soil resistivity changes seasonally, hence the performance of grounding systems, at DC and under high impulse conditions.

A critical review on soil ionisation modelling for grounding electrodes

open access: yesArchives of Electrical Engineering, 2016
Grounding electrode resistance non-linearly changes under impulse conditions due to soil ionisation phenomenon. Several models have been proposed to model soil ionisation for grounding electrodes applications.

Experimental Study on Gas Evolution Characteristics of DC Deep Well Grounding Electrodes

open access: yesIEEE Access, 2019
Deep well grounding electrodes (DWGE) have small occupied areas. The number of sub-ground electrodes is less than that of traditional vertical grounding electrodes. Thus, the former has a favorable development prospect.
