This report describes the activities that allowed for the creation of a new contamination level map in the Italian territory, within the scope of the collaboration agreement between RSE and TERNA. The multidisciplinary methodology used involved both an experimental approach, aimed at characterizing contamination levels, and a modeling approach, aimed at mapping. The latter is one of the first applications for estimating pollution levels to which electrical line insulators are exposed through a modeling system for assessing air quality. In 2021, both the mapping results and the field and laboratory activities supporting modeling studies of insulator contamination were consolidated.<\/p>\n","protected":false},"author":93,"featured_media":0,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false,"footnotes":""},"tags":[1324,1409,1340,1330,1379],"targets":[1317],"rapporti_tipologie":[762],"class_list":["post-192306","rapporti","type-rapporti","status-publish","hentry","tag-electricity-network-en","tag-isolators","tag-resilience","tag-security-en","tag-technologies-and-components","targets-research","rapporti_tipologie-report-en"],"acf":{"projects":{"ID":191042,"post_author":"464","post_date":"2024-07-10 15:54:47","post_date_gmt":"2024-07-10 13:54:47","post_content":"","post_title":"Components and materials for safety and resilience","post_excerpt":"The project aims to study and research innovative component and material solutions in order to increase the safety and resilience of the electrical system, also through new diagnostic methodologies which are necessary to cope with the new requirements of the grid and the changing environmental stresses to which it is subjected.","post_status":"publish","comment_status":"open","ping_status":"closed","post_password":"","post_name":"components-and-materials-for-safety-and-resilience","to_ping":"","pinged":"","post_modified":"2024-08-09 15:52:10","post_modified_gmt":"2024-08-09 13:52:10","post_content_filtered":"","post_parent":0,"guid":"https:\/\/www.rse-web.it\/progetti\/components-and-materials-for-safety-and-resilience\/","menu_order":0,"post_type":"progetti","post_mime_type":"","comment_count":"0","filter":"raw"},"order_posts":"","dont_show_search":false,"related_posts":false,"dont_show_hompage":false,"show_on_slider":false,"single_post_data":{"titolo_spot":"","post_content":"
This report describes the activities, also as a collaboration between RSE and TERNA, to create the final map of the contamination levels of insulators in the Italian electricity grid.
\nThe methodology included both experiments and modeling. The basis of the experimental data consists primarily of deposition measurements on 206 insulators of the electricity network taken between 2016 and 2018. The SMOKE-WRF-CAMx air quality modeling chain used by RSE allows for the calculation of severity indices throughout the national territory by means of numerical simulations. The harmonization between experimental and modeling data using data fusion techniques allowed for the definition of the final severity map.
\nThe results, although satisfactory, revealed the need to make further progress in the experimental characterization of the contamination process in order to obtain an increasingly accurate reconstruction of severity levels on the Italian territory. For this reason, both field and laboratory activities continued. The former are aimed at characterizing the vertical variability of the deposition and the effects of meteorological parameters, especially precipitation, on the deposit. At the same time, in collaboration with the Department of Environmental and Earth Sciences (DISAT) of the Universit\u00e0 degli Studi di Milano Bicocca (UNIMIB), the chemical composition of the non-soluble fraction of the insulator deposit was analyzed, to complement a similar activity carried out in previous years on the soluble fraction.
\nThe experimental activities, all substantially new, allowed us to further deepen our knowledge of the chemical-physical processes that determine the contamination of insulators and will allow us to further fine-tune also the corresponding modeling reconstruction.<\/p>\n","link_estreno":false,"scarica_file":[{"download_option":"download","file_name":"Download Report","download":{"ID":172627,"id":172627,"title":"21010364","filename":"21010364.pdf","filesize":3808764,"url":"https:\/\/www.rse-web.it\/wp-content\/uploads\/2022\/10\/21010364.pdf","link":"https:\/\/www.rse-web.it\/en\/rapporti\/mappatura-integrata-dei-livelli-di-contaminazione-sul-territorio-italiano-versione-finale\/attachment\/21010364\/","alt":"","author":"93","description":"","caption":"","name":"21010364","status":"inherit","uploaded_to":172626,"date":"2022-10-25 08:01:48","modified":"2022-10-25 08:01:48","menu_order":0,"mime_type":"application\/pdf","type":"application","subtype":"pdf","icon":"https:\/\/www.rse-web.it\/wp-includes\/images\/media\/document.png"}}],"button":{"text":"","link":""},"referente_group":false,"data_emissione":"2021-12-31","autori":"A.
