The goal of the research was to develop a control system for continuous monitoring of moisture control during the manufacturing process. We propose using a closed, low-energy microwave circuit, through a rectangular flow-through chamber with a unique profile. Results of the initial laboratory testing are promising. They indicate that this technique has the potential for an industrial application and may lead to a development of a simple and cost effective, continuous moisture control system. The research required designing a complex wave channel and high-precision manufacturing to build a laboratory prototype. The research team then conducted extensive testing of the prototype, including microwave leakage impact on the safety of the workplace. The paper also presents qualitative analysis.","PeriodicalId":165474,"journal":{"name":"2016 Progress in Applied Electrical Engineering (PAEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124097312","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 load is subject to the assessment of reliability of shock protection. The internal setup of the power inverter causes that the shorting circuit is different from circuits with linear components. The difference relies on the impossibility to determine the instant short-circuit impedance. In the paper on the example of an industrial installation with built-in power inverter, made in accordance with current requirements of in-rule standards and internal regulations at the considered plant, an analysis of reliability of used measures for anti-shock protection during a fault was carried out.","PeriodicalId":165474,"journal":{"name":"2016 Progress in Applied Electrical Engineering (PAEE)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126747819","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}

Such analyses are especially important in case of hybrid switching systems due to possibility of estimating system response during transient conditions (overvoltages, current distribution, power and energy dissipated at semiconductor branch, power and energy of electric arc, etc.). Presented model provides satisfactory convergence of simulation results with data obtained during experiments.","PeriodicalId":165474,"journal":{"name":"2016 Progress in Applied Electrical Engineering (PAEE)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131626414","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}
