Simulation and Experimental Investigation of DC Ice-Melting Process on an Iced Conductor
IEEE Transactions on Power Delivery, 2010Ice melting with dc is one of the key technologies to prevent the Chinese power grid from ice storms. Especially after the severe ice storm in the southern part of China in early 2008, dc ice-melting technology has drawn more attention than ever before.

Microstructure of Ice Accretions Grown on Aluminum Conductors
Journal of Climate and Applied Meteorology, 1983Abstract In order to study the microstructure of glaze and rime deposits formed on the conductors of power lines, ice accretions are grown on a slowly rotating aluminum cylinder placed in the working section of a wind tunnel. The growth conditions cover both dry and wet regimes in the air temperature interval between −2 and −15°C and are close to those

Effects of Ice Thickness on the Aerodynamic Characteristics of Crescent Shape Iced Conductors
Applied Mechanics and Materials, 2012Aerodynamic characteristics of iced conductors were investigated by the wind tunnel test. Under the homogeneous turbulence of 5% intensity, aerodynamic force coefficients of single and bundled conductors were obtained at wind angles of 0°~180°. The variation patterns of aerodynamic forces on the iced conductors with respect to wind angels of attack ...

Effect of ice loads on overhead-line conductors
Electronics and Power, 1965The authors have carried out tests on a 5-span section of 132-kV line to determine the jump height of the conductors after the release of simulated ice loads. They found that ice loads in excess of 1 lb/ft were sufficient to reduce the ground clearance of the lowest conductor below a safe level.

Material Issues in High-Ic Coated Conductors
2006Abstract : This three-year project started on May 1, 2003 and the report is the final report covering the whole project period. The overall goal of the project is to identify and eliminate current limiting factors in thick films HTS coated conductors and to develop novel tools for mapping non-uniformity of HTS coated conductors.

Numerical Analysis for Galloping of Iced Quad Bundle Conductors
Applied Mechanics and Materials, 2012In order to attain the purpose of anti-galloping, a simplified model for iced quad bundle conductors of three degrees of freedom in vertical, horizontal and torsional directions is established by means of the Hamilton principle, in which the effect of spacers stiffness and damping is considered.

Telemetering of Ice Loading on a Power Line Conductor
IEEE Transactions on Power Apparatus and Systems, 1965An ice load telemeter station employing unique methods of power supply and measurement has been designed and installed. The completely self-contained installation includes communication circuits, telemetry circuits, control, power supply from a 230-kV power line, and a radio telemeter circuit powered from and installed on an energized 345-kV conductor.
