Abstract
The industrial development and the increase in the use of fossil fuels have been accelerating global warming and climate change, thereby causing more frequent and intense natural disasters than ever before. Since electrical facilities are generally installed outdoors, they are greatly affected by natural disasters, thus accidents related to electrical equipment has been on the rise. In this paper, we present the risk rating associated with climate change by analyzing the statistics of electrical fires, electric shock accidents and electrical equipment accidents caused by domestic climate change. Further, we present a risk rating analysis model for electrical fires on a monthly basis through the data analysis of electrical hazards associated with various regional (metropolitan city) climatic conditions (temperature, humidity), and analyze the accident risk rating for natural disasters related to low and high voltage equipment. Through this risk analysis model for each region and type of equipment, we presented a basic prediction model for electrical hazards. Therefore, it is possible to provide electrical safety services in the future by displaying a risk prediction map of electrical hazards for each region and type of electrical equipment through web sites or smart phone apps using the presented analysis data. Further, efforts should be made to increase the robustness or reliability of electrical equipment in order to prevent electrical accidents caused by natural disasters due to climate change in advance.
Highlights
Abnormal climate phenomena appear in every corner of the world due to global warming, resulting in melting glaciers and rising sea levels but increasing the frequency of natural disasters such as droughts, floods, and typhoons
Because of global warming triggered by the increased use of fossil fuels with the industrial development, the climate is changing the environment such that extremely cold and hot temperatures are deepened and the frequency and intensity of lightning and typhoons are increased, which adversely affects electrical equipment [1,2,3]
In order to improve the predictability of electrical hazards, it is necessary to develop technologies that can respond to environmental changes by identifying, evaluating, and analyzing the risks through the analysis of the vulnerability of electrical equipment according to climate change [6]
Summary
Abnormal climate phenomena appear in every corner of the world due to global warming, resulting in melting glaciers and rising sea levels but increasing the frequency of natural disasters such as droughts, floods, and typhoons. Because of global warming triggered by the increased use of fossil fuels with the industrial development, the climate is changing the environment such that extremely cold and hot temperatures are deepened and the frequency and intensity of lightning and typhoons are increased, which adversely affects electrical equipment [1,2,3]. Abnormal climate phenomena such as sea level rise and changes in temperature and precipitation patterns due to continuous climate change are increasingly affecting various living environments and systems such as ecosystems, transportation, energy supply and demand, and infrastructure [4,5].
