Merjenje majhne porabe električne energije proizvodov skladno s standardom SIST EN 50564

KRAJNIK, NEJC (author), Begeš, Gaber (mentor)

Naša naloga je bila podrobno preučiti evropsko zakonodajo na področju omejevanja nizke porabe energije, ki jo predstavljata uredbi evropske komisije št. 1275/2008 in št. 801/2013 in s tem povezan referenčni standard za merjenje nizke porabe energije v Evropi in posledično tudi v Sloveniji SIST EN 50564. Iz standarda smo razbrali glavne težave in zahteve pri merjenju nizke porabe energije. Tako smo se osredotočili predvsem na izbiro primernih pogojev za preskušanje, izbiro primernega merilnega instrumenta, pravilen priklop merilnih instrumentov, izbiro primerne metode merjenja in izračun merilne negovosti. Kot glavno predpostavko smo predvideli, da izbrani parametri bistveno vplivajo na rezultat meritve nizke porabe energije. Za izbran proizvod smo nato v treh stanjih (stanje izključenosti, stanje pripravljenosti, aktivno stanje) primerjali vplive zgoraj omenjenih parametrov na končni merilni rezultat. V analizi smo vse dobljene rezultate ovrednotili s stališča standarda in za vsakega izmed njih ugotavljali skladnost.

Abstract

Our task was to study European legislation in the field of low power energy consumption which is covered by the Directive of European commission 1275/2008 and 801/2013 in conjunction with the relevant European and consequently Slovenian standard for low power measurement SIST EN 50564. From it we extracted the main problems and requirements and compared it to each other. We focused mainly on suitable conditions for testing, suitable measurement instrument selection, correct connection of the measuring instrument, suitable selection of method for measurement and measurement uncertainty calculation. Our main assumption was, that this parameters significantly affect low power measurement. Furthermore we compared influences of those parameters on final measuring result for a selected load in three different energy states (stand by mode, off mode, active mode). In the analysis we compared all the results and identified their compliance with the standard.
