Iyo yakakwirira-voltage simba mita inoiswa mubhokisi, isina watt- awa mita, inonzi yakasanganiswa transformer, uye AC oiri-yakanyudzwa yekunze mhando (yakakodzerawo mukati memba).Iyo metering mudziyo wekuyera zvakananga rinoshanda uye reactive simba mumitsetse yakakwira-voltage.Inoshanda kune matatu-chikamu AC ine rated frequency 50, 60Hz;10KV, 6KV, 3KV system network.Iyo ine mabhenefiti eiyo yakakwirira chaiyo, mwenje reset, kuisirwa nyore uye anti-kuba kwemagetsi.Nehuwandu hwemadhipatimendi emagetsi anogamuchirwa.
Iyo yechitatu-phase matatu-waya mita bhokisi inoumbwa maviri-single-chikamu voltage uye azvino ma transformer, uye matatu-chikamu mana-waya mita bhokisi inoumbwa neatatu single-phase voltage uye azvino transformer.Iyo casing yakaiswa pane pani, uye kunze kwekunze kwakashongedzerwa newatt-awa mita ye metering.
