20.500.12556/RUL-119854 Preverjanje kakovosti merilnikov električne energije po standardu Checking the quality of electricity meters in accordance with standard V zaključni nalogi sem predstavil postopek preizkušanja električnega števca. Preizkušanje je potrebno izvesti, da lahko proizvajalec svojo merilno opremo prodaja na trgu. V prvem delu naloge sem opisal teoretično ozadje električnih števcev, osnove statistike in merilne negotovosti. Prav tako sem opisal zakonsko ozadje, ki se tiče preizkušanja merilne opreme in bistvene zahteve in pogoje, ki veljajo za preizkušanje števcev električne energije. Preverjanje ustreznosti merilne opreme se izvaja po modulih – to so postopki za ugotavljanje ustreznosti. Preizkusi, ki sem jih izvajal so opisani v mednarodnem standardu. V njem so definirani pogoji, cilji in mejne vrednosti pogreškov za vsak posamezen preizkus. Števec sem preizkušal z merilnim sistemom vira napetosti, etalona in merilnih glav. Pogoje meritev sem nastavil s pomočjo računalniške programske opreme. Opisal sem tri preizkuse, ki sem jih opravil, merilne rezultate vsakega preizkusa in ugotovitev, ali je števec preizkus uspešno opravil. In this thesis I presented the process of testing an electricity meter. Testing needs to be done, so that the manufacturer can sell his measuring equipment on the market. In the first part of the thesis I described the theoretical background of electricity meters, basic statistics and measurement uncertainty. I also described the legal background, which applies to measuring equipment testing and basic demands and conditions which apply to electricity meters. Checking the adequacy of measuring equipment is implemented with the use of modules – processes for checking of compliance. The test I performed are described in an international standard. It consists of conditions, goals and limit values of measurement errors. I tested the meter with a measuring system, which consisted of a power source, a nationally accredited reference meter, and measuring heads. I set the test conditions with the use of computer software. I described three of the tests I performed, the measuring results and checking, if the meter passed the tests successfully. električni števec pogrešek standard negotovost electricity meter error standard uncertainty true false false Slovenski jezik Angleški jezik Zaključna naloga 2020-09-12 08:15:15 2020-09-12 08:15:20 2022-08-31 03:55:03 0000-00-00 00:00:00 2020 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 109943 29916419 1403.pdf 1403.pdf 1 2770C6A7FFD791FE2C1C7AF873FD5432 b4fb1ce291142bea0c00a8f939e01a2b0d9990b2d1ca48b2cde1c01bb05d0dba efd15112-a1b9-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=134590 Fakulteta za matematiko in fiziko 0 0 0
