Single-mamita magetsi agawo ndi zida zazikulu zoyezera mphamvu yamagetsi kwa anthu okhala m'nyumba ndi ogulitsa ang'onoang'ono. Kuchita kwawo ndi kudalirika kumagwirizana mwachindunji ndi chilungamo cha malo ogulitsa magetsi. Kuti muwonetsetse kulondola, chitetezo, ndi kusinthana, miyezo yokhazikika yokhazikitsidwa yakhazikitsidwa padziko lonse lapansi. dziko langa limatsatira kwambiri mulingo wadziko lonse wa GB/T 17215, potengera zofunikira za International Electrotechnical Commission (IEC).
Domestic Standard System
Miyezo ya mita ya magetsi ya dziko langa imodzi-pagawo limodzi ili pakati pa GB/T 17215.211-2021, "Zida Zoyezera Magetsi - Kudalirika - Gawo 211: Zofunikira Zodalirika pa Mamita Amagetsi," ndi GB21/T2}2{1}2}2 GB2{1}2}2} "Stationary AC Active Energy Meters (Class 1 ndi 2)." Zakale zimatchula zofunikira zamamita amagetsi malinga ndi kusintha kwa chilengedwe, mphamvu zamakina, komanso kukhazikika kwa nthawi yayitali; yotsirizirayo imatanthawuza magawo aukadaulo monga kalasi yolondola, kuyambira pano, ndi mtundu wamagetsi amtundu wa Class 1 ndi 2 yogwira mphamvu zamagetsi. Mwachitsanzo, malire olakwika a Class 1 metres ndi ± 1%, ndipo pamamita a Class 2, ndi ± 2%. Kulondola kuyenera kusungidwa mkati mwa 0.1Ib (10% ya maziko apano) mpaka Imax (pakali pano). Kuphatikiza apo, GB/T 15284-2022 imawonjezera ntchito ndi njira zoyesera zamamita amagetsi amitundu ingapo, zomwe zimafunikira thandizo pakukonza nthawi komanso kusungirako deta.
International Standard Harmonization
Padziko lonse lapansi, miyezo ya IEC 62053 (monga IEC 62053-}21:2020) imagwira ntchito ngati chitsogozo pakupanga mita imodzi{9}}pagawo limodzi ndipo ndi yogwirizana kwambiri ndi mfundo za dziko langa. Miyezo imeneyi imafotokoza mwatsatanetsatane momwe maginito amayendera (EMC), kupirira kutentha ndi chinyezi (monga kusiyanasiyana kwa madigiri -25 mpaka +60 madigiri ), ndi zofunika polimbana ndi kusokoneza. Kuphatikiza apo, miyezo ya m'madera monga EN 50470 ya EU ndi ANSI C12.10 yaku North America ikuphatikiza magawo osiyanasiyana okhudzana ndi kusinthasintha kwamagetsi ndi njira zolumikizirana (mwachitsanzo, infrared ndi RS-485). Tanthauzo la Kachitidwe ndi Kachitidwe
Dongosolo lokhazikika la miyezo limatsimikizira kuvomerezeka komanso kupita patsogolo kwaukadaulo kwa metering yamagetsi. Ndi chitukuko cha ma gridi anzeru, miyezo yaposachedwa ikuphatikiza pang'onopang'ono zofunikira pakuyankhulirana kwa HPLC, kusanja kwakutali, komanso kuwunika kwamphamvu. Opanga akuyenera kupititsa mayeso amtundu (monga kuyesa satifiketi ya CNAS ya China Electric Power Research Institute) kuti atsimikizire kuti akutsatira miyezo pa moyo wawo wonse wazinthu. M'tsogolomu, miyezo idzayang'ananso pa kutsika kwa - carbon metering ndi chitetezo pa netiweki, zomwe zidzachititsa kusintha kwa mamita a magetsi kukhala olondola kwambiri komanso luso lanzeru.
Mwachidule, mfundo zoyendetsera magetsi-gawo limodzi zimadza chifukwa cha kusamvana pakati pa ukadaulo ndi kufunikira kwa msika. Kukhathamiritsa kwawo kosalekeza kumapereka chithandizo chodalirika chaukadaulo pakuwongolera mphamvu padziko lonse lapansi.
