Impact of time parameters of lightning impulse on the breakdown characteristics of oil paper insulation

open access: yesHigh Voltage, 2016
At present, the insulation performances of electrical apparatus under lightning impulse voltages are always evaluated by the withstand test of standard lightning impulse voltage (1.2/50 µs), which is recommended by IEC Standard.

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.

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 ...

Characteristics of individuals who make impulsive suicide attempts [PDF]

open access: yesJournal of Affective Disorders, 2012
Previous research has identified only a few variables that have been associated with making an impulsive suicide attempt. The aim of the current study was to compare individuals who made an impulsive suicide attempt with those who made a premeditated attempt on both previously examined and novel characteristics.Participants were classified as making an

Pion-Nucleus Scattering at Medium Energies with Densities from Chiral Effective Field Theories [PDF]

open access: yes, 1998
Recently developed chiral effective field theory models provide excellent descriptions of the bulk characteristics of finite nuclei, but have not been tested with other observables. In this work, densities from both relativistic point-coupling models and
