Algorithm and framework for tower fault caused by ice overload
Introduction
Ice loads have caused several failures in towers associated a large overhead lines in mountains. If this transmission line is not design with reliability topology, as rings configuration. The cold phenomena, where each year the layer of ice and snow is increased during the last twelve years [1]. Due to the snow condition, above 4500 mamsl, therefore the developments, criteria and engineering, these countries should apply with care in these different tropical environmental conditions [3]. The analysis should identify the ice composition (ice, snow, frost) to describe the states of frozen water [4].
The objective of this research is to propose a root cause methodology for ice loads influence in transmission lines failures. The promising application of this methodology is to obtain new input data for an assessment for the transmission lines located above 4500 mamsl and the new projects.
This research has been structured as follows: The Section 2 described the methodology and description of the influence of the ice associated to transmission lines, loads, ice acceleration in structures, cables, national with international standards associated to recommend the best practices about this meteorological condition and risk. Section 3, a case study developed with the information of a critical overhead lines with structures in Andean mountain. In the Section 4 a discussion about the assessment of the structures and risk in these structures; finally in the Section 5 a new recommendation for the international standards.

Ice influnce description
- •
From the meteorological point of view, frozen water or ice can be classified into several types of ice or snow, depending on the mechanism of formation and properties, as follows:
- •
The hail is water frozen, droplets inside the clouds, which, after several cycles of accretion due to rising winds, fall to the ground due to excessive weight [9].
- •
The dry snow composed of water crystals, grouped in flakes that fall to the ground because of their weight, when the temperature is below 0 C. Snow is formed
Case study
A freeze defined as the meteorological event in which the temperature in the ground drops below 0 C, one of the conditions for the formation of ice sleeves. In fact, the formation of these ice mats only occurs in the range between 0 C and −10 C. At lower temperatures, the air devoid of moisture that can provide material for accretion by frosting and the possibility of over-cooled liquid rains, in the Fig. 5.
The map of Fig. 5, it indicates the area of Peru where there is a risk of frost. The
Discussion
The stage division of the ice disaster is composed of four stages: Preconditions (associated to the pre-failure period), steady-state progression and multiple failures (during disaster period) and restoration (post-failure period) [38]; recent papers have indicated effective resilience enhancement framework for towers installed, however, the recommendations for new assets are not considered.
The model data, loads, load combinations and the results of the analysis and Design (check for
Conclusion
This research has provided a new methodology in the Fig. 3 and an algorithm for the assessment for the design review and new projects for the Andean Mountain with an altitude over the 4000 mamsl. The ice load has big influence in the fragility and modelling of the overhead lines towers subjected to ice, wind and extreme environmental condition. Due to wind speed, the wind angle of the attack, the distance between towers, horizontal span during the normal operation and construction (rupture of

2022, Energy ReportsCitation Excerpt :According to the basic theory of RVM, not only the value of icing thickness, but also its variance caused by noise can be achieved, which gives statistical significance to the forecasting results and contributes to fault probability prediction of transmission line. The fault probability of a transmission line during an ice storm is determined by its mechanical strength and the icing load it with stands [19]. Considering the positive correlation between ice load and ice thickness, this article chooses ice thickness on behalf of icing load to calculate the fault probability of transmission line.
