Such demonstrator plays a big role in teaching both practical concepts and theoretical skills relevant for the topics on cabling, grounding and shielding. The success of the demonstrator relies on several factors, among which: its simplicity, its versatility, its possibility to confront measurements with actual field calculations and on the astonishing fact that these effects occur at 50 Hz. The demonstrator evidences current and magnetic field distributions in a hollow iron tube, for different connection configurations. Some key principles are evidenced, among others: skin effect, proximity effect and the principle of the path of least impedance.","PeriodicalId":376960,"journal":{"name":"2018 International Symposium on Electromagnetic Compatibility (EMC EUROPE)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127629534","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}

By using an in-house built framework, harsh reverberation room conditions are simulated. To compare the four variants, we established a baseline with unprotected data. The results show that certain variants of triplication are better equipped to deal with electromagnetic interference than others, depending on the environmental factors. In all cases, data triplication improves the data error rate of a communication channel. However, we also found that under specific but plausible conditions, all advantages of triplication are lost and the data error rate does not improve compared to unprotected data.","PeriodicalId":376960,"journal":{"name":"2018 International Symposium on Electromagnetic Compatibility (EMC EUROPE)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123620994","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}

This leads to systems which are very vulnerable to disturbances due to traction harmonics, or HF phenomena such as lightning, which quite often lead to availability problems. As railway systems are legacy systems, a change over to a modern earthing philosophy, which is needed in order to reach EMC, is quite often very difficult to implement. For a green field metro line in Doha, Qatar, however it was possible to develop and implement an earthing philosophy taking care of HF disturbances and of stray currents at the same time.","PeriodicalId":376960,"journal":{"name":"2018 International Symposium on Electromagnetic Compatibility (EMC EUROPE)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121700189","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}

Effectiveness of the technique is demonstrated with the experimental records of atmospherics. Application of a clustering algorithm allowed us to reveal different patterns of variations of the lower ionosphere effective height along different propagations paths. The distance finding accuracy of our tweek method had been roughly estimated by a comparison with independent data from the Blitzortung.org lightning location network to be less than 100 km with standard deviation less than 200 km in the range of distances from 500 to 1400 km.","PeriodicalId":376960,"journal":{"name":"2018 International Symposium on Electromagnetic Compatibility (EMC EUROPE)","volume":"196 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123231525","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}

In this work, a specialized strategy is developed to cancel the disturbing harmonics of stationary clocked systems. This strategy is refined by an adaptive approach to conveniently find the optimum signals for cancellation. As a special feature of this method, all troublesome effects, like delays or attenuations, can easily be compensated. From a basic theory, two implementation variants are derived: 1) Continuously Adapted Harmonics Cancellation (CAHC) and 2) Previously Adapted Harmonics Cancellation (PAHC). CAHC is implemented on an FPGA-system. The hardware, programming and performance of the utilized FPGA and its peripherals are transparently discussed. The effectivity of the method is demonstrated for a power electronic dc-to-dc converter.","PeriodicalId":376960,"journal":{"name":"2018 International Symposium on Electromagnetic Compatibility (EMC EUROPE)","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131426329","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}

Concerning immunity tests, for which transient high-altitude electromagnetic pulses (HEMP) are supplied to TEM waveguides [2], and general measurements with the topic of intentional and unintentional electromagnetic interference (IEMI/EMI), for which arbitrary ultra wideband signals are used, the specifications according to the IEC 61000-4-20 are not sufficient. The transmission characteristic of the TEM waveguide has to be validated for any arbitrary signal, what results in a huge effort in measurement and time. The knowledge of the transfer function would reduce this effort. The advantages and disadvantages of time and frequency domain approaches for evaluating the transfer function of TEM waveguides, especially G TEM cells, are discussed in this paper.","PeriodicalId":376960,"journal":{"name":"2018 International Symposium on Electromagnetic Compatibility (EMC EUROPE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128288800","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}
