PQ issues are a subset of electromagnetic compatibility (EMC), and identifying them can help track down problems in large networks. Commercial-off-the-shelf (COTS) sensors range from cheap smart plugs, with limited functionality and accuracy, to high-end measurement devices. For large-scale deployment and future research, a cost-effective solution is needed for distributed measurements. This letter discusses designing and evaluating a cost-effective PQ sensor that fits the gap between cheap smart plugs and high-end measurement devices. It is designed with expandability in mind while keeping the cost down. This allows the device to log other EMI parameters in the future by adding sensors without redesigning the device. An energy measurement accuracy of smaller than 1% is achieved, comparable to a class B energy meter of the EN-50470 standard. It can measure all the elementary electrical parameters so deviations to the EN-50160 can be logged in a (sub)second scale.","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"5 4","pages":"131-136"},"PeriodicalIF":0.0,"publicationDate":"2023-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76876609","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 main ideas of this letter are to determine possible EMI in the return traction current at the different traction systems of world railways and evaluate their influence on railway automatics. The following tasks were decided: comparing world power traction systems of railways and their automatics devices, estimating EMIs in the return traction current, and making conclusions for the future. The sources of external EMIs in the automatics and telecommunication circuits are very diverse: traction networks with harmonics and pulses, high-voltage power lines; lightning discharges, which have both dangerous and interfering effects under various conditions; and various industrial sources of electromagnetic fields (motors, generators, and welding units).","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"5 3","pages":"67-71"},"PeriodicalIF":0.0,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67867182","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}

We observed that designing an FPC for LCD TV modules that can minimize insertion loss (IL) and crosstalk in the channel is critical to successfully implementing multi-Gb/s signal characteristics in large-size and high-resolution LCD TV modules. To prove this experimentally, we investigated the trends of IL, impedance, and crosstalk, which are design parameters of simulation-based FPCs, and designed four FPC samples assuming their application to the intrapanel interface module of a real 75-in LCD TV. Then, based on the measured S-parameter model, the SI performance was verified and compared by measurement and simulation to demonstrate the validity of the proposed design guidelines. In conclusion, to achieve the SI characteristics of FPCs in LCD TV modules, it is necessary to consider minimizing IL and mitigating crosstalk more than any other electrical performance by enabling the differential P/N pairs to have a strong coupling relationship.","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"5 3","pages":"97-101"},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67868216","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 working principle and design process of the sensor are analyzed in detail while a finite-element simulation is carried out to verify the response characteristics of the sensor both in time and frequency domains, whose upper cut-off frequency can reach 680 MHz. For the purpose of assessing the actual detection capability of the sensor in HVDC converter stations, the sensor designed in this letter was used to detect the transient radiation E-field in the valve hall during the artificial short-circuit test in the Zhoushan ±200-kV five-terminal flexible dc transmission project. The measurement results of the transient E-field indicates that the sensor is able to respond instantaneously to the radiated E-field generated by the operation of the key power electronic equipment in the valve hall. It demonstrates that the designed sensor can be effectively applied in the scenario of the measurement of transient electromagnetic environment and noninvasive situational awareness technology for high-voltage devices in HVDC systems.","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"5 2","pages":"57-61"},"PeriodicalIF":0.0,"publicationDate":"2023-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67861416","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}
