Analytical Description of Overhead Transmission Lines Loadability

open access: yesEnergies, 2019
The loadability characteristics of overhead transmission lines (OHLs) is certainly not a new topic. However, driven by sustainability issues, the increasing need to exploit existing electrical infrastructures as much as possible, has given OHL ...

Efficient transient simulation of transmission lines [PDF]

open access: yes, 2002
The paper focuses on revealing the salient structural aspects of a new transmission-line model with a view to exploiting them for gains in efficiency and accuracy. The new transmission-line model has as its basis the Telegraphers Equations but the manner

Electromagnetic Transients in Multiconductor Transmission Lines

open access: yesJournal of Microwaves, Optoelectronics and Electromagnetic Applications, 2022
The theory of multiconductor transmission lines is based on the principle of superposition. According to this principle, any electric or magnetic field can be represented as the sum of individual electric or magnetic fields.

Analogue tachyons in SNAIL transmission lines

open access: yesNew Journal of Physics, 2023
Tachyons are hypothetical particles with imaginary mass that travel faster than light. However, methods to experimentally verify whether tachyons exist are lacking.

Fault Statistics and Analysis of 220-kV and Above Transmission Lines in a Southern Coastal Provincial Power Grid of China

open access: yesIEEE Open Access Journal of Power and Energy, 2020
Because the causes of transmission line faults are not known clearly at present, this paper proposes fault classification for transmission lines, and analyses the characteristics of different faults.

The effect of standing waves on the attenuation constant for a low‐loss rectangular waveguide

open access: yesElectronics Letters, 2021
When standing waves are present in a rectangular waveguide, the resistive losses in the walls are not uniformly distributed. This affects the measurement of the attenuation constant.

Failure Localization in Power Systems via Tree Partitions [PDF]

open access: yes, 2018
Cascading failures in power systems propagate non-locally, making the control and mitigation of outages extremely hard. In this work, we use the emerging concept of the tree partition of transmission networks to provide an analytical characterization of ...

Power lines and birds: An overlooked threat in South America

open access: yesPerspectives in Ecology and Conservation, 2023
Power lines endanger birds around the world, as a large number of them are killed every year through electrocutions and collisions. This problem can have severe consequences at population level, particularly for threatened species.

Time-domain parametric sensitivity analysis of multiconductor transmission lines [PDF]

open access: yes, 2011
We present a new parametric macromodeling technique for lossy and dispersive multiconductor transmission lines (MTLs). This technique can handle design parameters, such as substrate or geometrical layout features, and provide time-domain sensitivity ...
