Simulation Analysis of the Tensile Mechanical Properties of a Hydraulic Strain Clamp-Conductor System

open access: yesAdvances in Materials Science and Engineering, 2020
Herein, a three-dimensional (3D) finite element model of a strain clamp-conductor system is established, with an NY-300/40 compression-type strain clamp taken as an example.

Fast and accurate simulations of transmission-line metamaterials using transmission-matrix method [PDF]

open access: yes, 2008
Recently, two-dimensional (2D) periodically L and C loaded transmission-line (TL) networks have been applied to represent metamaterials. The commercial Agilent's Advanced Design System (ADS) is a commonly-used tool to simulate the TL metamaterials ...

Cooling a Micromechanical Beam by Coupling it to a Transmission Line

open access: yes, 2007
We study a method to cool down the vibration mode of a micro-mechanical beam using a capacitively-coupled superconducting transmission line. The Coulomb force between the transmission line and the beam is determined by the driving microwave on the ...

Analysis of Defect Detection for 10 kV Composite Insulator Based on the Microwave Method

open access: yesEnergies
During the long-term operation of composite insulators in transmission lines, they are easily affected by harsh environments, resulting in hidden defects such as surface contamination, shed damage, and adhesive failure. A defect detection method based on

Continuous variable quantum cryptography using coherent states [PDF]

open access: yes, 2001
We propose several methods for quantum key distribution (QKD) based upon the generation and transmission of random distributions of coherent or squeezed states, and we show that they are are secure against individual eavesdropping attacks.

Dual theory of transmission line outages

open access: yes, 2017
A new graph dual formalism is presented for the analysis of line outages in electricity networks. The dual formalism is based on a consideration of the flows around closed cycles in the network.

Transmission Line Analogy for Relativistic Poynting-Flux Jets [PDF]

open access: yes, 2013
Radio emission, polarization, and Faraday rotation maps of the radio jet of the galaxy 3C 303 have shown that one knot of this jet carries a {\it galactic}-scale electric current and that it is magnetically dominated.

Monitoring voltage collapse margin by measuring the area voltage across several transmission lines with synchrophasors

open access: yes, 2014
We consider the fast monitoring of voltage collapse margin using synchrophasor measurements at both ends of transmission lines that transfer power from two generators to two loads.

Stabilizing control for power converters connected to transmission lines [PDF]

open access: yes, 2007
This paper proposes a switching control strategy for the set-point stabilization of a power converter connected via a transmission line to a resistive load.

The Progress and Prospect of Gap Breakdown Characteristics and Discharge Mechanisms of Overhead Transmission Lines Under Vegetation Fire Conditions

open access: yesEnergies
Wildfires frequently occur, posing a significant threat to the operational stability of transmission lines across mountainous forest areas. Therefore, this paper reviews numerous studies conducted by domestic and international scholars on the gap ...
