Because of the size and production cost reductions as well as the oil's high level of biodegradability, this could result in an increase in the dielectric strength of insulating fluid. Since transformers are mainly used for outdoor applications, understanding the capability of insulating fluid to withstand lightning discharge is a vital issue. This study used experimental analysis to compare the lightning discharge performance of pure sunflower oil and sunflower oil modified with SiO2 (Nano) at various weight-per-volume concentrations of 0.01 %, 0.05 %, and 0.1 %. This experimental work was conducted with 1.2/50 µs of standard lightning impulse voltage with positive polarity. The result illustrated that the nano-modified sunflower oil had greater lightning impulse withstand strength than the pure sunflower oil.","PeriodicalId":36296,"journal":{"name":"Journal of Water and Environmental Nanotechnology","volume":"188 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88210514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The withstand capabilities of mineral oil is studied under different experimental conditions such as varying electrode gap distance, electrode type, type of nanofiller and concentration of fillers. Experiments are conducted for electrode gaps of 5mm and 10mm. Different electrode configurations such as needle sphere and needle plane electrodes are used. Nanofillers such as SiO2 and Carbon Quantum Dots treated SiO2 nanoparticles are used in various concentrations such as 0.01%wt. 0.05%wt and 0.1%wt of mineral oil. Comparison is done for positive and negative polarities of lightning impulse test voltages.

Photocatalytic activity of synthesized iron oxide nanoparticles was determined against Methylene blue (MB) dye in aqueous medium. Iron oxide nanoparticles acted as a photocatalyst and decompose the dye under solar irradiation. Results show that 73 % of degradation efficiency was attained after 150 minutes with a nanoparticle dosage 0.5 mg/L which makes the IONPs as potential applicant for various effluent treatment methods. Further the results indicate that the efficiency increases with increasing pH and decrease with increasing the MB dye dosage. Antimicrobial activity of IONPS was studied against E.coli and S. aureus.

The design of such sensors assumes importance as the technology enables reproducibility, reliability, portability and cost-effective sensing in real time. This paper presents the frequency response of a 300 MHz ST-Quartz SAW delay line device fabricated with uniform IDTs. Based on the first order Impulse response model and employing a unique custom made MATLAB algorithm, the device is accurately modelled. The results obtained are analyzed to ultimately help in the effective design, development and modelling of such devices as application specific sensors.
