Three-phase electricity meters are core instruments used in power systems to accurately measure three-phase AC energy consumption. Lawv tau dav siv hauv kev lag luam, kev lag luam, thiab cov txheej txheem loj hauv thaj chaw yog ua raws li kev ntsuas hluav taws xob hauv hluav taws xob lossis hluav taws xob. Los ntawm kev sau peb - theem voltage thiab cov cim tam sim no, siv lub zog, thiab pom tseeb, thiab pom tseeb tias qhov tseeb kev tsom xam ntawm hluav taws xob lub zog.
Kev tsim qauv, tsoos peb {{-} theem hluav taws xob meters feem ntau ntiav cov neeg siv hluav taws xob feem ntau siv. Qhov kev sib txuam ntawm kev sib nqus flux tsim los ntawm cov hlua hluav taws xob thiab cov kauj tam sim no drives kev sib hloov ntawm Aluminium disk, nrog kev sib hloov ceev proctional rau lub zog. Lub iav kis tsheb sib kis tau cov kev sib hloov thiab qhia txog kev nyeem ntawv. Niaj hnub no hluav taws xob peb {{4 4}}}}} {{precision analog {}} cov hloov dua siab tshiab (ADCS).

Cov hluav taws xob hluav taws xob meters muaj cov qhab nia siab dua, muaj zog tiv thaiv kab mob xws li, thiab cov cab kuj kis tau, lossis cov cab kuj sib kis, tswjfwm kev tswj hwm kev txawj ntse. Cov ntsiab lus zoo ntawm peb-}}}}}}}}}}}}}}}}}}}}}}}}}}}} agicity thiab unbalanced peb- theem teeb. Cov khoom siv muaj feem ntau siv peb-theem fais fab tsim kho tau, thiab cov hluav taws xob metres yuav tsum ntsuas qhov tseeb ntawm txhua theem lub zog los xyuas kom meej qhov tseeb ntawm cov ntaub ntawv hluav taws xob. Tsis tas li ntawd, cov hluav taws xob niaj hnub no feem ntau sib xyaw ua ke xws li Kev Ntsuam Xyuas Kev Sib Koom Tes, thiab siv cov ntaub ntawv kev txhawb nqa rau cov xwm txheej kev saib xyuas thiab cov neeg siv hluav taws xob ua kom zoo.
Ntawm daim ntawv thov, xaiv ntawm peb -}}}}}}}}}} kev txiav txim siab ntawm ntsuas hluav taws xob, ntau yam, thiab ib puag ncig sib xyaw. Piv txwv li, muaj cov xwm txheej muaj metrarios yuav tiv thaiv cov thauj khoom siab thiab cov tsev lag luam hnyav, thaum ua lag luam ua lag luam ua ntej kev sib txuas lus sib txuas lus sib txuas lus sib txuas lus sib xws. Nrog rau kev txhim kho cov pob ntse, cov hluav taws xob ntse meters nrog cov peev txheej i6 3}} Lub Zog Nyiaj Siv Kev Tswj Xyuas thiab kev txhim kho hluav taws xob ntxiv thiab cov neeg siv kev sib koom tes.
Yav tom ntej, peb {-}}}}}} {}} -- {1} Kev ua kev sib xyaw ua ke rau kev tsim kho cov txheej txheem, txhim khu kev qha, thiab lub zog txhim kho, thiab lub zog txhim khu kev qha.
