However, there is still a lack of research on the design of the internal fuse for HV shunt capacitors. In this article, an experimental platform is built to investigate the effect of the diameter on the fusing characteristics of the fuse. The maximum nonfusing current action integral and the minimum fusing current action integral of fuses with different diameters in the range of 0.3–0.7 mm are obtained. Then, the equivalent circuits of the capacitor unit are analyzed when there is a short between terminals or element breakdown. The current flowing through the fuses with different diameters and lengths is studied, and the current action integral is calculated. Comparing them with the maximum nonfusing current action integral and the minimum fusing current action integral obtained from the experiments, the selection range of fuse diameter and length can be determined. In order to verify the rationality of the fuse design method, the internal fuse of a 668 kvar HV shunt capacitor used in ultrahigh-voltage (UHV) transmission projects is designed and validated experimentally. This article will provide a reference for the internal fuse dimension design of HV shunt capacitors.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142175294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the physical structure of the launcher, finite element models and mathematical models of three systems were established. The circuit characteristics, motion characteristics, electromagnetic characteristics, and mechanical characteristics of the three systems were solved using the finite element analysis method, and the accuracy of the finite element method was verified by numerical analysis results. The data showed that the DFAS has a low current characteristic with a peak current of 21.1 kA, while the DFAS and APAS have energy conversion efficiency of 29.7% and 24.4%. APAS has good electromagnetic protection capability, with a magnetic induction intensity above its armature not exceeding 0.008 t within 0.4 ms. The stress in most areas of the armature and drive coil of the three systems is less than 42.54 MPa. The results showed that the DFAS and APAS have certain engineering application prospects, while the ICAS is not conducive to engineering applications.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142175296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Also, the large sheath thickness compared to the low mean free path at atmospheric pressure and large plasma flow velocity forbids the use of conventional collisionless stationary plasma theory for probe analysis. In this work, a system has been envisaged to sample the CAP jet into a low-pressure chamber using an orifice for Langmuir probe-based plasma diagnostics. Simulations were performed to ascertain the possibility of generating and maintaining a low pressure inside such an open chamber, while the increase in gas velocity can be kept at a minimum value. Based on the simulation results, a chamber was fabricated and the results were verified experimentally. A Langmuir probe based on a double probe configuration was developed to acquire the I–V curve from the sampled plasma. The effects of sheath collisions, fluid velocity, and pressure differential were accommodated in the probe analysis to calculate the electron temperature and ion number density.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141944255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The water sample having high total dissolved solids (TDSs) is treated by inserting a 10 mm plasma jet into the water surface. The generated PAW is analyzed mainly by evaluating nitrate, nitrite, oxidation-reduction potential (ORP), TDS, electrical conductivity (EC), and pH. The results clearly illustrate an increase in the concentration of nitrate, nitrite, and ORP for an increase in cold plasma treatment time from 3 to 15 min. The maximum nitrate concentration of 155 ppm has been obtained in the water (TDS ~1000 ppm) for 15 min of cold plasma treatment. The pH concentration of the generated PAW remains almost constant. The generated PAW has also been tested for its suitability in germination enhancement and plant growth. The results noticeably indicate higher germination rate, vigor index, length, and weight of root and shoot of seeds irrigated with PAW as compared to tap water. The fungal growth in PAW irrigated seed saplings is also negligible than that of tap water irrigated seeds in 15 days of continuous observation period. This study would be very useful for the design and development of PAW systems for water samples with high TDS for agriculture applications.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141944257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
