Their primary source are nonlinear loads which process the energy of fundamental harmonic on the higher harmonics energy. Such load can be used in the stiffness test of the supply network. An arc furnace is one of more often met industrial nonlinear load. The paper deals with the balanced three-phase circuit of the arc furnace in which arcs voltages are proportional to the sign of arcs currents. The equation of fundamental harmonic and equations of higher harmonic phasic currents were determined. Next the higher harmonics of currents and further fundamental harmonic of currents were designated analytically. On its base equivalent diagrams of nonlinearities were described. The analyzed load has the univalent characteristics (without hysteresis) and also does not cumulate the energy. During the work the circuit of the furnace on terminals of the power source it is observed greater inductances than during short circuit tests. This difference arise of the equivalent inductance of the electric arc, calculated for first of harmonic. The total reactive power of the nonlinearity being with the sum of all harmonics reactive powers, computed as proportional to the product of the voltages and the time derivative of the current is equal to the zero. All that concerns the circuit with the countable number of the zero crossing of currents. Equations of the considered circuit describe also other nonlinear receiver, less burdensome for the environment and the modelling than the three-phase electric arcs.","PeriodicalId":397235,"journal":{"name":"2017 Progress in Applied Electrical Engineering (PAEE)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125925606","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}

Currently, there are few descriptions of vacuum switch models used for capacitive circuits switching on. More often researchers focus on vacuum switch models used for switching of the circuits (also previous works of the Authors) and even more often models used for switching of the inductive circuits. In this work authors have focused on phenomena of switching on by vacuum switch in capacitive circuits which in the literature is not often described and which in its character differs significantly from the processes taking place during switching off. In the model, presented in this paper, authors proposed beside the voltage-current control a new approach of modelling of the mechanism of contact bounce, based on the Matlab library element “sldemo_bounce”. The verification of the correctness of the model has been done in capacitive circuit during switching on of the capacitor batteries with different parameters (capacities) and neutral point connection. This model have not been analysed in inductive circuits.","PeriodicalId":397235,"journal":{"name":"2017 Progress in Applied Electrical Engineering (PAEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130611254","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}
