Performance of Practical Grounding Systems under High Impulse Conditions

open access: yesEnergies, 2018
This paper investigates the factors affecting the impulse characteristics of purposely built grounding systems. We installed 2 m × 2 m grounding systems in four different sites with different soil resistivity values.

Analysis on frequency and impulse characteristics of grounding grid

open access: yesThe Journal of Engineering, 2019
Studying the frequency and impulse characteristics of grounding grids is of great reference value for the optimal design of the substation. As the frequency increasing, the variation trend of the grounding resistance under different conditions is not ...

Associations of Functional and Dysfunctional Impulsivity to Smoking Characteristics [PDF]

open access: yesJournal of Addiction Medicine, 2012
Although the relation between impulsivity and smoking is well-documented, one model of impulsivity that has received little attention in the addiction literature separates impulsivity into 2 dimensions: functional impulsivity (tendency to make quick effective decisions) and dysfunctional impulsivity (tendency to make quick ineffective decisions).This ...

Characteristic impulse-response grammians

open access: yesElectronics Letters, 1991
A new Grammian known as the characteristic impulseresponse Grammian is introduced. It is an extension of the impulse-response Grammian presented by Agathoklis and Srceram. An important property of the characteristic impulse-response Grammian which can be useful in modelreduction application is also derived.

Electrical Tree Initiation Properties in Cross-Linked Polyethylene Under DC-Impulse Composite Voltages

open access: yesIEEE Access, 2018
DC cables may be subjected to impulse overvoltage during operation, which may cause electrical tree inside the cable insulation. So, it is necessary to investigate the influence of impulse voltage on the insulation of dc cable.
