Abstract
Mjerenje impedancije kratkospojne petlje u današnje vrijeme je puno lakše nego u prošlosti. Prije se rezultat impedancije kratkospojne petlje mogao dobiti samo računanjem, a to traje dugo i nije toliko precizno kao instrumenti, jer oni mogu pokazati impedanciju u svakom trenutku. U današnje vrijeme za mjerenje koristimo instrumente poput Metrela Eutrotesta 61557. Korištenje je puno lakše i brže jer na instrumentu osim impedancije kratkospojne petlje (Z) može se vidjeti i struja kratkog spoja (ISC), impedancija realnog dijela (R) i impedancija induktivnog dijela (XL). Osim mjerenja tu su objašnjeni bitni pojmovi poput impedancije, struje kratkog spoja te instrumenta za mjerenje Metrela Eurotesta 61557. Navedeni su bitni pravilnici koje treba proučiti i pridržavati se tijekom mjerenja. Na kraju je objašnjen postupak koji se izvodi tijekom zadanog mjerenja i tijek mjerenja. Na kraju rada u tablici su prikazani rezultati koji su dobiveni prilikom izvođenja mjerenja.
Abstract (english)
Today measuring of fault loop impedance is much easier than in the past. In some earlier times, the result of fault loop impedance could only get by calculating, but that takes a long time and is not accurate as the instruments, because they can show the impedance at any time. Nowadays for measuring we use instruments like Metrel Eutrotes 61557. The using is much easier and faster because on instrument except fault loop impedance (Z) we can see short circuit current (ISC), real part of impedance (R) and inductive part of impedance (XL). Except measuring, here are presented important conceps as impedance, short circuit current and measuring instrument Metrel Eurotest 61557. Also here are important regulations which need to be observed and comply during the measurment. Finally there is explained procedure which is preformed during a measurment and flow of measurment. At the end of this work, the results that were obtained in the measurement where shown in the table.
