The possibility of application of vibration diagnostics methods for assessing the technical condition and predicting the remaining life of the vehicle's clutch under operating conditions is explored. The authors proposed a way to improve the on-board diagnostics system with the help of a set of methods, rules and means necessary for measuring the parameters of the system's operation, converting them into diagnostic parameters to assess the technical state of the system under study.

In the case of application in field environment, several optimizations and first field measurements had to be performed with the goal of receiving boundary conditions for the field application, which will be specified in this article. The main part of the paper will be focused on a presentation of field measurement results of medium voltage power cables within challenges of multiple reflections and impedance matching. Furthermore, opportunities and solution approaches for reference simulation and measurements in field environment will be discussed.","PeriodicalId":211666,"journal":{"name":"2018 International Conference on Diagnostics in Electrical Engineering (Diagnostika)","volume":"279 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131921451","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 angle value is hard to accurately obtained because of field interferences and other causes. The leakage current is so small which the signal path parameters and other interference contribute a fairly large error. In this paper, an equivalent circuit model of capacitive equipment considering multicomponent parameters is established. By analyzing the influence of electromagnetic field distribution and wiring modes on the leakage current path, an equivalent circuit model considering many influencing factors is proposed. This paper also analyzes the influence of aging, temperature and humidity on the equivalent circuit parameters, explores the causes of the current measurement error, and finally obtains the transfer function of the leakage current and the path component parameters.","PeriodicalId":211666,"journal":{"name":"2018 International Conference on Diagnostics in Electrical Engineering (Diagnostika)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130935641","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}

Therefore, it is reasonable to monitor their aging process and expected reliability. There are, however, many electrical, thermal, mechanical and radiation stresses, which, through time, can influence the occurrence of insulation degradation. Assessment and evaluation of the condition of cable insulation is supposed to be carried out periodically, during the scheduled outages and maintenance activities. Accordingly, it is necessary to carefully select the proper efficient diagnostic methods and different scrutinises, particularly studied and purposeful for determining the aging grade and overall adequacy of the cable insulation. To avoid unplanned failures with loss of critical equipment, the insulation must be properly tested. Therefore electrical and non-electrical diagnostic methods are used to ensure proper assessment of cable insulation deterioration. This paper reports on experience with application of different diagnostic methods boosting tendency to improve monitoring of the condition of the cable insulation in the NPP Krško, The diagnostic testing and measurements on cables recommended to be done in nuclear power plant respecting a good practice of asset maintenance management is discussed.","PeriodicalId":211666,"journal":{"name":"2018 International Conference on Diagnostics in Electrical Engineering (Diagnostika)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132892341","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}

Then wide-band voltage of 30Hz $sim$ 1MHz is rebuilt based on two paths of signals.

Up to the year 2000 a clear vertical distribution structure and the corresponding load-flow was visible. Since that time, due to the increasing number of regenerative production plants in the lower distribution network levels, an additional horizontal utilization takes place at an increasing number of time intervals. As a result, the weaker, lower distribution structures, in which more than 75% of renewable energy systems feed in, are increasingly burdened. In combination with the lack of opportunities, e.g. the willingness of the population to demand side management and the still limited storage possibilities this means, that the network resources in these areas are partially heavily loaded. In the following paper, models and methods will be presented, which will open up opportunities to limit the load flow to the physically required by an intermittent localization of the energy usage.","PeriodicalId":211666,"journal":{"name":"2018 International Conference on Diagnostics in Electrical Engineering (Diagnostika)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114953780","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}
