Temporal distribution of the electrical energy on an exploding wire
(Cambridge University Press, 2016-06)
An exploding wire system has been experimentally studied by the observation of its plasma dynamics and the electrical energy delivered by the supporting circuit to the metallic wire. Plasma radial expansion has been obtained ...
Eigenvalue analyses for non-transposed three-phase transmission line considering non-implicit ground wires
(2012-12-11)
This paper presents a method for analyzing electromagnetic transients using real transformation matrices in three-phase systems considering the presence of ground wires. So, for the Z and Y matrices that represent the ...
Electrical behavior of exploding copper wire in ambient air
(American Institute of Physics, 2018-07)
This work experimentally investigates the electrical behavior of an exploding wire when the initial energy of the system varies from 28 to 709 J. This experiment uses 50-um-diameter, 33-mm-long copper wires. The wire is ...

On the Measurement of the Resistivity in an Exploding Wire Experiment
(Institute of Electrical and Electronics Engineers, 2018-03)
Explosion of a metallic wire due to a large electrical current can be used for studying metallic states difficult to reach with other methods. Due to experimental constraints, direct measurement of the voltage drop across ...
Quantum theory of the effect of grain boundaries on the electrical conductivity of thin films and wires
(Elsevier, 2015)
We calculate the electrical conductivity of a metallic sample under the effects of distributed impurities
and a random distribution of grain boundaries by means of a quantum mechanical procedure based on
Kubo formula. ...
The effect of surface roughness and grain-boundary scattering on the electrical conductivity of thin metallic wires
(Wiley, 2015)
We report a new formula for the electrical conductivity of a thin wire of rectangular cross-section, obtained from an exact solution of the Boltzmann equation by assuming perfectly diffuse surface scattering and absence ...
