Semidziyo yepakati mumunda wemagetsi metering, kuyerwa kwemamita emagetsi kunotarisisa mamiriro ayo anoshanda uye kuvimbika kwedata. Sainzi kutsanangura chiyero chemamita kwakakosha pakuona kwakaringana simba metering, kuenderana kwehurongwa, uye kuchengetedzwa kwemushandisi.
Kubva pakuona kwehunyanzvi, kuyerwa kwemamita emagetsi kunowanzo kuumbwa nezviratidzo zviviri zvakakosha: "rated current" uye "maximum current." Kune imwe chete-chikamu chemagetsi emagetsi emagetsi, semuenzaniso, yakayerwa ikozvino (eg, 5A, 10A) inomiririra kukosha kwekutanga kwenguva yakareba-yakagadzikana kushanda pasi pemamiriro ekushanda, ukuwo iyo yakanyanya ikozvino (eg, 60A, 80A) inomiririra ipfupi yemamita{11}yenguva inokwana kushivirira kuremerwa. Kupfuura kukosha uku kunogona kukonzera kupisa kwechikamu kana kuwedzera kukanganisa kuyerwa. Kune matatu-mamita emagetsi emaindasitiri, kuyerwa kwemuyero kunofanirwa kuenderana nepamusoro pezvinodiwa. Mamwe mamodheru anotsigira kuyerwa kwakakura kwe0.1A kusvika 200A ne0.5S-level yechokwadi, uye inogona kutowedzerwa kusvika pa kiloampere renji nekunze shunt.
Izvo zvinodiwa zvemamita siyana zvinosiyana zvakanyanya munzvimbo dzakasiyana dzekushandisa. Mumamiriro ekushandiswa kwemagetsi ekugara, mamita anowanzo vhara huwandu hwemumba hunosvika 3kW kusvika 10kW (inoenderana nemhepo inosvika 13A kusvika 45A). Izvi hazvizadzise zvinodiwa nemidziyo yemagetsi zuva nezuva, asi zvinobvumirawo kuti pave nekubatanidza-midziyo yemagetsi yakakwira yakaita semaairconditioner uye maheater emvura emagetsi. Maindasitiri uye ezvekutengeserana mamiriro anoda yakakwirira dynamic renji. Semuenzaniso, makamuri epa data anogona kunge akashongedzerwa nemamita akangwara ane huwandu hwe200A kana kupfuura kuti atarise iyo pakarepo peak mutoro wemasevha masumbu. Mumagetsi emagetsi anogona kudzokororwa{{11}masisitimu akabatana, mamita anofanirwawo kutsigira kuyerwa kwebidirectional (chizvarwa uye kushandiswa), uye dhizaini yerudzi runofanirwa kunyatso tora kumberi nekumashure uko.
Zvakakosha kuziva kuti kusarudza chiyero chemita hakusi nani. Kuwedzeredza kwakakwira calibration currents kunogona kuderedza metering senitivity panguva dzemutoro wakaderera (somuenzaniso, mita ye100A inogona kuwedzera kukanganisa pakuyera 5A), nepo yakaderera huwandu hunogona kuwedzera njodzi yekuremerwa. Mazuvano ma smart metres anodzikamisa tension iyi kuburikidza ne-range otomatiki switching tekinoroji (sezvakaita madhizaini akafararira ekuchinja). Mamodule ekukurukurirana anogona zvakare kurodha maprofiles munguva chaiyo, zvichibatsira vashandisi kukwirisa mashandisiro avo emagetsi. Kumisikidza kuyerwa kwemamita zvese chinhu chakaomarara chinodiwa chezviyero zvehunyanzvi uye chinhu chakakosha mukuona kutonga kwakanaka kwesimba. Sezvo masisitimu emagetsi achiwedzera hungwaru, chaiyo yemamita renji inogadziriswa icharamba ichinyanya kunetseka kune indasitiri.
