Research on conductor icing of overhead transmission lines

2011 International Conference on Consumer Electronics, Communications and Networks (CECNet), 2011
With 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.

Numerical Investigation on Transmission Line Conductor Icing

Applied Mechanics and Materials, 2014
Ice accretion on transmission line conductor exists widely in nature, which can bring a lot of hazards. It is important and necessary to obtain characteristics of ice on different conductors for analyzing ice hazards or developing ice protection technology.

Effect of ice loads on overhead-line conductors

Electronics and Power, 1965
The 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.

Microstructure of Ice Accretions Grown on Aluminum Conductors

Journal of Climate and Applied Meteorology, 1983
Abstract 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

Mathematical Models for Ice Accretion on Conductors using Free Streamline Theory

IMA Journal of Applied Mathematics, 1988
It is the purpose of this paper to develop theoretical models of rime ice accretion and snow loading on a single conductor. The ice-accretion kinetics are formulated in terms of separated or free streamline airflow, assuming that the conductor does not twist under the eccentric ice loading on the windward side.

Telemetering of Ice Loading on a Power Line Conductor

IEEE Transactions on Power Apparatus and Systems, 1965
An 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.
