Arbitrary Grounding [PDF]

open access: yes, 2021
The aim of this paper is to introduce, elucidate and defend the usefulness of a variant of grounding, or metaphysical explanation, that has the feature that the grounds explain of some states of affairs that one of them obtains without explaining which ...

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.

Investigative Study of Vertical Electrodes Encased in Concrete/Mortar with Various Sizes of Air Voids

open access: yesEnergies, 2021
Ionisation can occur in the soil when high impulse currents are subjected to grounding systems. This occurrence is generated by a difference in the dielectric strength value between the soil and air voids.

A pulse generator with inductive energy storage for measuring the grounding resistance of transmission line towers

open access: yesVestnik MGTU, 2018
The pulse method may be used to measure the footing resistance of transmission towers with overhead grounding wires. Measuring systems that obtain the time dependent transient impedance may be used to measure the low-frequency resistance of transmission ...

Harmonic Current Distribution in Grounding Systems of Cabled Medium Voltage Grids during Single-Pole Ground Fault

open access: yesEnergies, 2021
The design of every power supply system must guarantee the safety for human life even in the event of a fault. Due to the system change in the electrical power supply, the fault current contains more and more unknown shares of current harmonics ...
