Amamitha kagesi-ezigaba ezintathu angamathuluzi abalulekile asetshenziswa kumasistimu kagesi ukukala ngokunembile-isigaba sesithathu sokusetshenziswa kwamandla e-AC. Asetshenziswa kakhulu ezimbonini, ezentengiselwano, nasezinhlelweni zokuhlala ezinkulu.Izimiso zabo zobuchwepheshe zisekelwe ekungenweni kukagesi noma ubuchwepheshe be-electronic metering. Ngokuqoqa-izigaba ezintathu zikagesi kanye namasignali amanje, babala amanani anqwabelene wamandla asebenzayo, asebenzayo, namandla abonakalayo, ekugcineni bathole ukuhlaziya kwezibalo zenani lamandla kagesi.
Ngokwesakhiwo, amamitha kagesi wezigaba ezintathu-ejwayelekile ngokuvamile asebenzisa idizayini ye-electromagnetic mechanical. Ukusebenzisana kwe-magnetic flux okukhiqizwa amandla kagesi kanye namakhoyili amanje kushayela ukuzungezisa kwediski ye-aluminium, ngesivinini sokuzungezisa ngokulingana namandla. Indlela yokudlulisa igiya iqoqa ukuzungezisa futhi ibonise ukufundwa. Amamitha kagesi wezigaba ezintathu zesimanje-zezigaba ezintathu ancike kuma-microprocessors kanye-ne-analog enembayo-kuya{7}}kuma-digital converters (ADCs). Benza isampula ngokuqondile amanani asheshayo-ezigaba ezintathu zevolthi kanye neyamanje, babale amandla asheshayo kusetshenziswa ama-algorithms okucubungula isignali yedijithali, futhi bahlanganise idatha yamandla. Amamitha kagesi we-elekthronikhi anikeza ukunemba okuphezulu kokulinganisa, ukungaphazamiseki okuqinile, kanye nokusekela amakhono okuxhumana okukude njenge-RS-485, i-carrier wave, noma ukudluliswa okungenantambo, ukusiza ukuphathwa kwegridi yamandla okuhlakaniphile. Inzuzo eyinhloko-yamamitha kagesi ezigaba ezintathu isekukwazini kwawo ukuthwala imithwalo yezigaba ezintathu-ebhalansile futhi engalingani. Izisetshenziswa zemboni ngokuvamile zisebenzisa ugesi wezigaba ezintathu ukuze kuthuthukiswe ukusebenza kahle, futhi amamitha kagesi kufanele alinganise ngokunembile isamba se-vector samandla esigaba ngasinye ukuze kuqinisekiswe ukunemba kwengqikithi yedatha yamandla. Ngaphezu kwalokho, amamitha kagesi wesimanje ngokuvamile ahlanganisa izici ezifana nokuhlaziywa kwe-harmonic, izibalo zesidingo, nokugawulwa kokunqamuka kukagesi, ukuhlinzeka ngosekelo lwedatha lokuqapha isimo segridi kanye nokwenza kahle komsebenzisi kwamandla kagesi.
Ezingeni lohlelo lokusebenza, ukukhethwa-kwamamitha kagesi ezigaba ezintathu kudinga ukucatshangelwa kwamandla kagesi alinganiselwe, ububanzi bamanje, nokuhambisana kwendawo. Isibonelo, izimo zezimboni zingadinga amamitha ukuthi amelane nokuguquguquka okuphezulu komthwalo nezimo zokushisa ezinzima, kuyilapho izakhiwo zezentengiselwano zibeka phambili ukuhambisana kokuxhumana. Ngokuthuthukiswa kwamagridi ahlakaniphile, amamitha kagesi ahlakaniphile anamandla e-IoT aya eba yinsakavukela, asekela{3}}impendulo yentengo kagesi yesikhathi sangempela kanye nokuphathwa kokufinyelela kwensiza yamandla esabalalisiwe, athuthuke kakhudlwana ukusebenza kahle kwesistimu yamandla nokusebenzisana komsebenzisi.
Ngokuzayo,-ubuchwepheshe bemitha kagesi bezigaba ezintathu buzoqhubeka buthuthukela ekunembeni okuphezulu, ukunethiwekha, kanye{1}}nokuhlanganiswa kwemisebenzi eminingi, kube ingqalasizinda eyinhloko yokwakha uhlelo lwamandla olusebenza kahle, oluthembekile, noluzinzile.
