CT ni ngombwa mubikorwa bitandukanye, harimo:
Sisitemu zo Kurinda: CT ni ntangarugero mu kurinda ibyuma birinda ibikoresho by'amashanyarazi imizigo irenze urugero. Mugutanga verisiyo yagabanutse yubu, bashoboza relay gukora idahuye ningaruka nyinshi.
Ibipimo: Mubucuruzi ninganda, CT zikoreshwa mugupima ingufu zikoreshwa. Bemerera ibigo byingirakamaro gukurikirana umubare wamashanyarazi akoreshwa nabakoresha benshi badahuza neza ibikoresho bipima kumirongo yumuriro mwinshi.
Kugenzura ubuziranenge bw'imbaraga: CTs ifasha mu gusesengura ubuziranenge bw'amashanyarazi mu gupima imiterere igezweho n'ibindi bipimo bigira ingaruka ku mikorere ya sisitemu y'amashanyarazi.
Gusobanukirwa Impinduka za voltage (VT)
A Umuyoboro wa voltage(VT), izwi kandi nka Potential Transformer (PT), yagenewe gupima urugero rwa voltage muri sisitemu y'amashanyarazi. Kimwe na CT, VT ikora ku ihame rya induction ya electromagnetic, ariko irahuzwa hamwe nu muzunguruko ugomba gupimwa voltage. VT ikamanuka hejuru yumubyigano mwinshi kugeza kurwego rwo hasi, rushobora gucungwa neza rushobora gupimwa neza nibikoresho bisanzwe.
VT isanzwe ikoreshwa muri:
Igipimo cya Voltage: VTs itanga ibisobanuro nyabyo bya voltage yo kugenzura no kugenzura intego mugusimbuza no gukwirakwiza imiyoboro.
Sisitemu zo Kurinda: Kimwe na CT, VT zikoreshwa mu kurinda kurinda kugira ngo hamenyekane imiterere ya voltage idasanzwe, nka voltage nyinshi cyangwa amashanyarazi, ibyo bikaba bishobora kwangiza ibikoresho.
Gupima: VT nayo ikoreshwa mubikorwa byo gupima ingufu, cyane cyane kuri sisitemu y’amashanyarazi menshi, bigatuma ibikorwa bipima ingufu zikoreshwa neza.
Itandukaniro ryingenzi hagatiCTna VT
Mugihe CTs na VT byombi aribintu byingenzi muri sisitemu yamashanyarazi, biratandukanye cyane mubishushanyo mbonera, imikorere, hamwe nibisabwa. Dore itandukaniro ryingenzi:
Imikorere:
CTs ipima ikigezweho kandi ihujwe murukurikirane n'umutwaro. Batanga ibipimo byamanutse bigereranwa nibyibanze.
VTs ipima voltage kandi ihujwe hamwe nu muzunguruko. Bamanuka hejuru ya voltage hejuru kurwego rwo hasi rwo gupima.
Ubwoko bwihuza:
CTs ihujwe murukurikirane, bivuze ko ibyagezweho byose bitembera muburyo bwambere.
VT ihujwe kuburinganire, ituma voltage hejuru yumuzingi wibanze gupimwa nta guhagarika urujya n'uruza.
Ibisohoka:
CTs itanga icyiciro cya kabiri nigice cyumubyigano wibanze, mubisanzwe murwego rwa 1A cyangwa 5A.
VT itanga voltage ya kabiri nigice cya voltage yibanze, akenshi ikagera kuri 120V cyangwa 100V.
Porogaramu:
CT ikoreshwa cyane cyane mubipimo bigezweho, kurinda, no gupima murwego rwohejuru.
VT ikoreshwa mugupima voltage, kurinda, no gupima mubisabwa na voltage nyinshi.
Ibishushanyo mbonera:
CT igomba kuba yarateguwe kugirango ikore imigezi myinshi kandi akenshi irapimwe ukurikije umutwaro wabo (umutwaro uhujwe na kabiri).
VT igomba kuba yarateguwe kugirango ikore voltage nyinshi kandi igenzurwa hashingiwe ku kigereranyo cy’imihindagurikire ya voltage.
