The volume of this kind of cost depends on the consumption and tariffs set by suppliers. The branches of the economy are mutually related at the stage of production and sales. A number of macroeconomic indicators, which are quite complex systems, characterizes their activities. Identify the impact on them of tariffs on energy expended and various services is quite a challenge. Nevertheless, this issue is very important, since the establishment of tariffs for energy, material resources and services is sometimes carried out without taking into account their influence on the final macroeconomic indicators and the welfare of the population. In this article, an attempt is made to highlight the impact of tariffs on the main macroeconomic indicators of the economy. It turned out that the higher the tariffs, the greater the intermediate consumption and the lower the gross added value and the volume of the gross domestic product, as well as the volume of final consumption. To ensure sustainable development of the economy, it is necessary to coordinate the establishment of energy tariff levels, taking into account the welfare of the population.","PeriodicalId":403279,"journal":{"name":"2017 International Conference on Electromechanical and Power Systems (SIELMEN)","volume":"2017 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130417943","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 use of underloaded electrical power transformers is an important factor in the operation of electrical installations at a power factor (cosϕ) below the one permitted by national and international norms (neutral power factor), presenting multiple disadvantages both economic and financial, and technical. In this respect, replacing these transformers with some lower power (optimal for the new requirements of the consumer) is the accepted solution in practice. Thus, choosing and sizing the transformer with optimum load and reduced losses is very important for users. This paper presents a method for analyzing the optimal load of transformers based on the calculation of electrical energy transited and energy losses. As a solution for optimal use of electrical power transformers, there are some advantages of the \"rewired transformers\".","PeriodicalId":403279,"journal":{"name":"2017 International Conference on Electromechanical and Power Systems (SIELMEN)","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126260202","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}

When the country lack both own primary energy resources and generation capacity, being imposed to import its, and requiring for this more diversified network, having at the same time obsolete power system from the technical point of view, and not only, which was designed and constructed in the years of \"60–70 of the past century, the modernization and refurbishment measures need to be implemented. To reach a high level of energy security, a serious intervention should be done in each segment of the energy chain: generation, transmission, distribution, storage, supply and consumption. The advantage of implementation of intelligent micro grids (MG) innovational concept at the level of distribution and low voltage network for consumers energy supply have been proved worldwide. In order to initiate measures of such nature, present paper emphasizes real conditions and background in the Republic of Moldova.

The electromagnetic field generated by high-voltage overhead power lines and high-voltage equipment may be harmful, especially to those operating these installations. Taking into account the exposure time of workers in the case of maintenance in high voltage installations, there is a need for a thorough analysis of the real stress on workers and methods to reduce exposure to electromagnetic field. When using non-ferromagnetic materials, time-varying magnetic flux B determines an induced electric field in the shield material, producing an induced electric field, which will generate a magnetic field opposite to field from the outside. The shielding factor depends only on the electric conductivity of the shield material. In the case of ferromagnetic materials, the shielding factor of the shield depends on the penetration depth of the magnetic field, so depends on permeability and electric conductivity of the material. The paper aims to perform a comparative analysis of the methods for magnetic field shields, using different materials with different magnetic and electrical properties.","PeriodicalId":403279,"journal":{"name":"2017 International Conference on Electromechanical and Power Systems (SIELMEN)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114375437","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}
