Substation measurement data acquisition

U ovom radu dan je osnovni koncept prikupljanja podataka iz transformatorske stanice pomoću multimetra i programske podrške LabVIEW-a. Na početku je dan uvod u transformatore koji se koriste za transformaciju struja i napona kako bi ih se skaliralo na mjerljive vrijednosti. Slijedi opis značajki multimetra SIEMENS Sentron PAC3200 i programske podrške LabVIEW-a. U sklopu poglavlja o LabVIEW-u se posebno napominje grafički pristup programiranju kao glavna značajka LabVIEW-a. U posljednjem poglavlju razrade se objedinjuje teorija prethodnih poglavlja te se daje konkretan primjer prikupljanja mjernih podataka s transformatorske stanice koja se nalazi na Fakultetu elektrotehnike i računarstva u Zagrebu. This graduation work presents basic concept of gathering data from transformer station using multimeter and LabVIEW software. In the beginning, what's given is introduction to transformers, which are used for transforming current and voltage to measurable values. Following chapter about transformers, this work describes basic features of SIEMENS Sentron PAC3200 multimeter and LabVIEW software. The LabVIEW chapter emphasizes graphical programming approach, which is LabVIEW's main feature. In the last chapter of this work, theory of past chapters is summed up, and concrete example of gathering measurement data from transformer station, which is located in Faculty of electical engineering and computing in Zagreb, is given.
