Ihame rya Transformer

Mu murongo w'amashanyarazi, guhinduka, guhererekanya, gukwirakwiza, no gukoresha ingufu, imigezi iratandukanye cyane, kuva kuri amper nkeya kugeza ku bihumbi mirongo amperes. Kugirango byorohereze gupima, kurinda no kugenzura, bigomba guhinduka muburyo bumwe. Mubyongeyeho, voltage kumurongo muri rusange ni ndende cyane, nko gupima mu buryo butaziguye ni bibi cyane. Impinduka zubu zifite uruhare rwo guhinduka no kwigunga amashanyarazi.
Kubyerekana-ubwoko bwa ammeter, icyiciro cya kabiri cya transformateur yubu ni ampere-urwego (nka 5A, nibindi). Kubikoresho bya digitale, ibimenyetso byiteganijwe ni milliampere (0-5V, 4-20mA, nibindi). Umuyoboro wa kabiri wa miniature ihinduranya ni milliampere, kandi ikora cyane nkikiraro hagati ya transformateur nini na sampling.
Impinduramatwara ya miniature nayo yitwa "ibikoresho bigezweho". .
Impinduramatwara iriho ubu isa na transformateur kandi ikora ikora ihame rya induction ya electromagnetic. Transformator ihindura voltage naho transformateur ihindura ikigezweho. Guhinduranya kwa transformateur ya none ihujwe numuyoboro wapimwe (umubare wimpinduka ni N1) byitwa guhinduranya kwambere (cyangwa ibanze ryambere, guhinduranya byambere); kuzunguruka (umubare wimpinduka ni N2) uhujwe nigikoresho cyo gupima cyitwa icyiciro cya kabiri (cyangwa icyiciro cya kabiri)
Ikigereranyo kiriho hagati yicyuma cyibanze cya I1 cya transformateur yubu hamwe na I2 ya kabiri ihindagurika byitwa igipimo nyacyo kigezweho K. Ikigereranyo kigezweho cya transformateur iyo ikorera kumuyoboro wagenwe byitwa impinduka zubu zahinduwe, ihagarariwe na Kn.
Kn = I1n / I2n
Imikorere ya transformateur yubu (CT) nuguhindura ibyibanze byambere bifite agaciro kanini mumashanyarazi ya kabiri hamwe nagaciro gake binyuze mumibare runaka yo guhinduka kurinda, gupima nibindi bigamije. Kurugero, impinduramatwara igezweho ifite igipimo cya 400/5 irashobora guhindura umuyoboro nyawo wa 400A muburyo bwa 5A.
