Assessing the Superhydrophobic Performance of Laser Micropatterned Aluminium Overhead Line Conductor Material

IEEE Transactions on Power Delivery, 2021
Overhead electric supply lines are subject to water and ice accumulation, causing noise and weight increase, and leading to faults or failures. In this research, micro-textures were laser-ablated on aluminium substrates representative of overhead line ...

Study on Aerodynamic Instability and Galloping Response of Rail Overhead Contact Line Based on Wind Tunnel Tests

IEEE Transactions on Vehicular Technology, 2023
The overhead contact line is a tensioned cable structure erected along the railroad to power the electric train. Under the wind load, the galloping of OCL caused by aerodynamic instability may form a large amplitude, which is a big potential threat to ...

A study of line overhead in the Arpanet

Communications of the ACM, 1976
The form, extent, and effect of the communication line overhead in the ARPANET are considered. The source of this overhead is separated into various levels of protocol hierarchy and the characteristics of each level are summarized. Then the line efficiency for various models of system use is studied. Some measurements of line efficiency for the ARPANET

Overhead line switching transients

Journal of Physics A: Mathematical and General, 2002
Summary: An efficient method is presented for the determination of switching transients in overhead lines. This new approach is based on the partial fraction expansion of the network functions in the Laplace \(s\)-domain. Newton's algorithm is used to locate the poles in the complex \(s\)-plane.
