The equipments and installations may be located in controlled areas or may be added to an existing assembly. The purpose of the paper is to present aspects of electromagnetic compatibility between the components of the railway system and the adjacent area. This is all the more so as the rail uses very large power. The railway system is an integrated system in which electricity is used both for the main purpose of propulsion of the train and for other uses (such as signaling, telecommunication installations, powering of control centers, etc.). Thus, problems can arise not only in the railroad itself and in the power network, but also in the associated systems. In the paper a series of electromagnetic field modeling is carried out near the overhead catenaries and around the earthling return circuit. The purpose of this paper is to validate the initial design of the railway installation in terms of electromagnetic compatibility. The effects of the electromagnetic field on humans, even though there is the term electrosmog, are not to be neglected. The railway system must operate safely, so its operator must ensure that the infrastructure is immune to electromagnetic disturbances or to know them very well.","PeriodicalId":129030,"journal":{"name":"2019 International Conference on Electromechanical and Energy Systems (SIELMEN)","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133499242","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}

For a straightforward case (single wire), it is easier to verify the match between the result obtained by analytical calculation and the one acquiredby simulation. The CST Studio simulation software mainly provides the required simulations. It has been developed a model that allows the choice of the soil conductivity value. Higher values for magnetic fields were obtained by up to 70% in the case of good ground conductivity (o=100S/m), compared with the practically insulating soil (o = 0.1 S/m). For mutual validation, these simulations were compared with those obtained using EMFACDC software. It then went on to a more common but complicated case, precisely, the three-phase, double, high voltage network. The simulations showed less influence of image currents due to mutual compensation. In the end, concrete recommendations have been done on methods for reducing the magnetic emissions due to Overhead High Voltage Power Lines (OhHVPL) from the soil conductivity perspective.","PeriodicalId":129030,"journal":{"name":"2019 International Conference on Electromechanical and Energy Systems (SIELMEN)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132732160","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 presented method, also known as ”imaging method” uses a conventional digital photo camera calibrated to measure luminance and present it as a luminance map presenting the values for the entire area for which the photo is taken. The particular study presented is for a conflict area, but this method can be used for straight road measurements as well. In this particular study it is presented a very important conflict area in Iaşi City, Romania Country, on Bucsinescu road for which a lighting calculation is made using DIALux 4.13 and the results are compared to the values measured by the camera. One of the conclusions is that values are very sensible to the properties of the asphalt and the position of the observer, but still very close to the values calculated to the DIALux Software. This is a strong statement of the accuracy and usability of this method and a clear example of the benefit one would encounter if this measurement method would be considered as a standard for reception in street lighting systems upgrades and extensions.","PeriodicalId":129030,"journal":{"name":"2019 International Conference on Electromechanical and Energy Systems (SIELMEN)","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130827599","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 asynchronous motor with multiple/double cages rotors has a large application in fans and water pumps for various industrial and irrigation systems, as well as in lathe and drilling machines. So, to calculate its characteristic is crucial to improve the performances of the system. After a brief introduction about the constraints of systems with multiple cage asynchronous motors, paper propose a short review on theoretical background of these machines.

Microprocessor-based relays are often called numerical relays, because analog inputs are converted into numbers that are processed by the relay. At present, there is a tendency to replace the classical devices in the protection, measurement, signaling and control systems with digital relays that achieve better performance. Among the advantages of the new digital relays we can enumerate that they can incorporate more functions into one device.
