The two current shunts which underwent the comparison program are the STL reference standard shunt for Europe and Africa and the coaxial shunt type 200kA manufactured by IPH Berlin which stands for the C.L. - ICMET standard shunt. Both of the shunts are of the same manufactory type with similar technical characteristics, thus providing the ability of comparison. The comparison results, proving little errors (in comparison with the magnitude order of the CMC having been stated for the C.L. for this kind of tests) related to the scale factor of the IPH-ICMET shunt, are consistent with the results of all its Calibration Certificates, so this is a witness of the traceability of the measurement results in C.L. On the other side, the IPH shunt and the HBM digitizers are the main error component sources of the Current Reference Measuring System belonging to C.L.-ICMET. By two different checking undertakings and by the calibration certificates, we conclude that the errors introduced by the digitizers are also very small. The results here-above showed that the uncertainties associated to the scale factor of the Reference Measuring System are much smaller than the “CMC” having been stated for it under accredited regime.","PeriodicalId":327050,"journal":{"name":"2014 International Conference on Applied and Theoretical Electricity (ICATE)","volume":"189 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122975918","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 metal enclosed switchgear upgrading is based on the patent proposal no. A/00230/14.03.2013 for this purpose and aims at increasing the reliability in the supply of electricity. The modernization consists in eliminating the existing deficiencies of secondary distribution metal enclosed switchgear by replacing the air or SF6 switching devices with vacuum switching devices, by merging the separation and interruption functions (of nominal currents, excess currents or fault currents) in the same multipurpose vacuum switching device, supplemented by the use of another vacuum switching device, for the earthing function. In this way it will be possible for the remote controls to be assigned to all the functions of the metal enclosed switchgear [separationinterruption (simultaneously) or earthing] with vacuum switching devices, thus providing a mechanical endurance with at least a size grade greater than the existing ones. Due to the possibility for remote control of all the functions of the metal enclosed switchgear, the maintenance costs for the entire lifespan will be lower, and the duration of network reconfiguration will be significantly reduced as opposed to current duration, ensuring a higher performance of the supply of electricity to the customers. By using silicone and composite insulation for the general bars of the metal enclosed switchgear and the vacuum switching devices of its equipment, with a leakage path to the mass higher than the existing ones, it will be possible for the metal enclosed switchgears, which have their cable outgoing insulated with sealed potheads to operate in severe environmental conditions, and to be tested and certified according to CEI/ST62271-304/2008.","PeriodicalId":327050,"journal":{"name":"2014 International Conference on Applied and Theoretical Electricity (ICATE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114348265","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}

An virtual instrument with multiple options for selecting the analyzed parameters is described. The values of motor measurement voltages, currents and speed are read from a specified folder. With present virtual instrument it can be see the motor currents, voltages and speed waveforms and from the acquired data and recorded a set of parameters are computed. Boolean selector determine which signals are selected from the original seven signals (three current, three voltages and speed). It can be extract portions of data from the input signals. The extract portion is defined by the begin of offset (point of start) and the length (end the extraction). This instrument allow timing and transition measurements such as: pulse duration (pulse width), duty cicle (duty factor), preshoot (%), overshoot (%), slew rate. Also this virtual instrument allow to find the first highest (maximum) and the lowest (minimum) point in a set of values in signals of currents, voltages or motor' speed and find the time of the maximum and minimum values so determined. Knowing these values can be determined the range from the lowest point to the highest point in a set of motor's start current and voltage.","PeriodicalId":327050,"journal":{"name":"2014 International Conference on Applied and Theoretical Electricity (ICATE)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124288690","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}
