Parameter Study on Galloping of Iced Bundled Conductors
2010 Asia-Pacific Power and Energy Engineering Conference, 2010The aerodynamic coefficients of iced quad-bundled conductor varying with attack angle determined by wind tunnel test are presented. A cable element with torsional degree-of-degree used to simulate the iced conductor is obtained in ABAQUS software by releasing the two bending degrees-of-freedom and setting the material to be incompressible.

Impact of icing severity on corona performance of glaze ice-covered conductor
IEEE Transactions on Dielectrics and Electrical Insulation, 2017This paper presents the results of laboratory experiments carried out on an ac-energized stranded conductor subjected to simulated glaze icing, which were conducted in a corona cage located in an artificial climate chamber. With the increase of icing duration, the grow of icing severity of conductors lead to the corona onset voltage fell from 54.8 to ...

Research on conductor icing of overhead transmission lines
2011 International Conference on Consumer Electronics, Communications and Networks (CECNet), 2011With the development of power and extreme weather increasing, icing of transmission lines caused a series of accidents whose harm and impact also expanded. In this paper the ice-prone areas and its influence were described. At the same time icing conditions and the main types of icing were analyzed.

Anti-Icing Mechanism for a Novel Slippery Aluminum Stranded Conductor
ACS Applied Materials & Interfaces, 2023The icing of transmission conductor seriously threatens the safe operation of power grids. Slippery lubricant-infused porous surface (SLIPS) has shown great potential for anti-icing applications. However, aluminum stranded conductors have complex surfaces, and the current SLIPSs are almost prepared and studied on small flat plates.

High-Ic HoBCO Coated Conductors by PLD Method
IEEE Transactions on Appiled Superconductivity, 2005Ho/sub 1/Ba/sub 2/Cu/sub 3/O/sub x/ (HoBCO) coated conductors by using Pulsed Laser Deposition (PLD) have been developed on textured Ni-alloy substrates. Hetero-epitaxial growth of CeO/sub 2//YSZ/CeO/sub 2/ was developed to introduce in-plane alignment for buffer layers. CeO/sub 2/ seed and cap layers were deposited by RF sputtering.

Ice formation on different hydrophobic aluminum conductor surface
2010 IEEE International Symposium on Electrical Insulation, 2010Ice accretion on high voltage power lines is a severe problem for power network and it can cause insulator flashover, wire breakage and tower falling down. In the present work, different hydrophobic surfaces were deposited on aluminum conductor and the ice accretion process on these hydrophobic aluminum surfaces were studied in an artificial climatic ...

Influence of AC electric field on conductor icing
IEEE Transactions on Dielectrics and Electrical Insulation, 2016Atmospheric icing of conductors is a major issue for the safety, design and operation of transmission lines. In the presence of an electric field on the surface of the conductor, ice accretion mechanism behaves differently compared to non-energized state.

High field Ic characterizations of commercial HTS conductors
Physica C: Superconductivity and its Applications, 2015Abstract High field I c performance of commercial high T c superconductors, in view of applications such as an insert magnet for high field generation beyond 20 T, needs to be directly measured as no comprehensive relationships exist with the readily accessible 77 K self-field data. We have constructed and tested the measurement probes for high

Effect of temperature on galloping of iced conductors
Advances in Structural Engineering, 2017This article investigates the effect of temperature on galloping of iced conductors, accounting for the influence of sagging and geometric nonlinearity. By extending Irvine’s cable theory to thermo-elasticity problems, an analytical model is proposed to evaluate the effect of thermal stress on galloping of transmission lines.
