The publication illustrates an optical sensor for monitoring transformer oil. It was implemented in a plastic optical fiber that serves as an optical platform for the sensing element, i.e., a layer of molecularly printed polymer, which is a robust, reproducible, and low-cost receptor for chemical marker in the insulating oil matrix. This optical sensor was evaluated on the detection of a chemical byproduct of transformer paper degradation, furfuraldehyde (2-FAL).<\/p>\n
The performance of the optical sensor was tested on samples of used insulating oil leaked from ex-serviced instrument transformers and compared with the results of standard methods applied to the same samples. The good agreement achieved emerging from the comparative analysis confirms the ability of the optical sensor to detect low 2-FAL concentrations directly in mineral oil, without any treatment or dilution of the oil.<\/p>\n","scarica_file":[{"download_option":"download","file_name":"Download Memory","download":{"ID":105303,"id":105303,"title":"18007562-318998.pdf","filename":"18007562-318998.pdf","filesize":1411900,"url":"https:\/\/www.rse-web.it\/wp-content\/uploads\/2021\/03\/18007562-318998.pdf","link":"https:\/\/www.rse-web.it\/en\/pubblicazioni\/toward-an-optical-monitoring-of-chemical-markers-in-transformers-insulating-oil-318998\/18007562-318998\/","alt":"","author":"464","description":"18007562-318998.pdf","caption":"","name":"18007562-318998","status":"inherit","uploaded_to":136958,"date":"2021-12-31 00:00:00","modified":"2021-03-17 14:28:37","menu_order":0,"mime_type":"application\/pdf","type":"application","subtype":"pdf","icon":"https:\/\/www.rse-web.it\/wp-includes\/images\/media\/document.png"}}],"link_estreno":false,"button":{"text":"","link":""},"referente_group":false,"data_emissione":"2019-12-31","autori":"L.
