Elektrilevi on Eesti suurim jaotusvõrgu ettevõte, enamik kliente tarbib elektrienergiat
Elektrilevi jaotusvõrgust madalpingel. Tarbimispunktides on vajalik elektrienergia
mõõtmine.
Selle töö sisu on enimkasutatavate mõõtesüsteemide võrdlemine ja analüüsimine,
selgitamine, mis on mõõtesüsteemide võimalused ning miks on mõõtesüsteemide valik
selliseks kujunenud. Lisaks selgitatakse võrgus tekkiva reaktiivenergia nähtust ja selle
mittevajalikkust. Mõõtesüsteemide valik ei ole hoomamatult kirju, sellise valiku tekkimisel
on kindlad põhjused: erinev side keskhaldussüsteemiga, tarbijate peakaitsmete suurused,
elektrienergia tootmise võimalikkus, tarbijate soov mõõtesüsteemi mitte uuendada.
Elektrilevi is the biggest distribution company on elekctrical energy, most clients in Estonia recieve their electricity through Elektrilevi power grid. It is necessery to meter electricity in every consumption point. The aim is to examine most common measuring systems - what are the features and explaining current selection of measuring systems. In addition the occurance of reactive energy in the distribution powergrid is also explained.. There are certain reasons for the situation of measuing systems: varying communication connection, selection of main circuit-breakers, possibility of producing electrical energy by consumers, headstrong consumers who are not letting to upgrade their measuring systems. The selection of measuring systems is currently not too overly excessive.
