Ma transformer amakono, nthawi zambiri amatchedwaMa CT, ndi zinthu zofunika kwambiri mu makina amphamvu. Zimagwira ntchito yofunika kwambiri pa chitetezo ndi kuyeza, mosiyana ndi ma transformer wamba. Munkhaniyi, tifufuza kusiyana pakati pa ma CT ndi ma transformer wamba ndikuphunzira momwe ma CT amagwiritsidwira ntchito poteteza.
Choyamba, tiyeni tifufuze kusiyana pakati pa ma transformer a CT ndi achikhalidwe. Ma transformer achikhalidwe makamaka amapangidwa kuti azitha kusamutsa mphamvu zamagetsi pakati pa ma circuits mwa kuwonjezera kapena kuchepetsa kuchuluka kwa magetsi. Omwe amagwiritsidwa ntchito kwambiri m'ma network ogawa magetsi, magetsi amakwezedwa kuti atumize magetsi pamtunda wautali ndipo magetsi amatsitsidwa kuti agwiritsidwe ntchito ndi ogula.
Motsutsana,ma transformer amagetsiZapangidwa mwapadera kuti ziyeze kapena kuyang'anira momwe magetsi akuyendera mu dera lamagetsi. Zimagwira ntchito motsatira mfundo ya kulowetsedwa kwa magetsi, mofanana ndi transformer wamba. Komabe, kuzungulira koyamba kwa CT kumakhala ndi kutembenuka kamodzi kapena kutembenuka kangapo, zomwe zimathandiza kuti ilumikizidwe motsatizana ndi kondakitala wonyamula magetsi. Kapangidwe kameneka kamathandizaCTkuyeza mafunde amphamvu popanda kutayika kwakukulu kwa mphamvu. Kuzungulira kwachiwiri kwa CT nthawi zambiri kumayesedwa kuti ndi mphamvu yotsika, zomwe zimapangitsa kuti chipangizocho kapena chipangizo choteteza chikhale chotetezeka.
Tsopano, tiyeni tipitirire ku kufunika kwa CT pa ntchito zoteteza. CT imagwiritsidwa ntchito kwambiri m'makina amagetsi kuti zitsimikizire chitetezo cha zida, mabwalo ndi antchito. Amagwira ntchito yofunika kwambiri pozindikira zolakwika, mafunde ochulukirapo komanso mikhalidwe yosazolowereka yogwirira ntchito. Poyesa molondola mafunde, CT imayambitsa chipangizo choteteza chomwe chimalekanitsa gawo lolakwika ndi makina ena onse, kuti zisawonongekenso.
Chipangizo chodzitetezera chomwe chimagwiritsidwa ntchito limodzi ndi ma CT ndikutumiza. Relay ili ndi udindo wowunikira mtengo wamagetsi ndi kuyambitsa kutsegulidwa kapena kutsekedwa kwa circuit breaker kutengera makonda ndi mikhalidwe yomwe yakhazikitsidwa kale. Mwachitsanzo, ngati circuit yochepa kapena current yochulukirapo ichitika, relay imazindikira vutoli ndikutumiza chizindikiro cha ulendo ku circuit breaker.CTkuonetsetsa kutikutumizaimalandira chithunzi cholondola cha mphamvu yamagetsi yomwe ikuyenda mu dera, zomwe zimapangitsa kuti pakhale chitetezo chodalirika.
Ma CTamagwiritsidwanso ntchito poyesa ndikuwunika magawo amagetsi. Mu machitidwe amagetsi, ndikofunikira kudziwa kuchuluka kwenikweni kwa mphamvu yomwe ikuyenda m'mabwalo osiyanasiyana. CT imalola kuyeza molondola, kuonetsetsa kuti magetsi akuyenda bwino komanso kuti katundu aziyenda bwino. Miyeso iyi ingagwiritsidwe ntchito polipira, kuyang'anira mphamvu komanso kukonza zodzitetezera.
Kuphatikiza apo, ma CT amagwiritsidwa ntchito kwambiri m'mafakitale ndi makina okhala ndi katundu wambiri wamagetsi. Amapereka njira yowunikira kuchuluka kwa magetsi ndikupeza zolakwika zilizonse, monga kudzaza kwambiri kwa injini kapena kutsika kwa magetsi. Mwa kuzindikira mwachangu mavutowa, njira zodzitetezera zitha kuchitidwa kuti zipewe kulephera kwa zida zodula kapena nthawi yogwira ntchito.
Mwachidule, ngakhale kuti ma CT ndi ma transformer okhazikika amagwira ntchito motsatira mfundo ya electromagnetic induction, amagwira ntchito zosiyanasiyana. Ma CT amapangidwira kuyeza ndi kuteteza magetsi. Kapangidwe kake kapadera kamathandiza kuti athe kuyeza molondola mafunde amphamvu komanso kupereka mphamvu yotetezeka komanso yosiyana yogwiritsira ntchito zida ndi zida zodzitetezera. Kaya kuzindikira zolakwika, kuonetsetsa kuti magetsi ali otetezeka kapena kuyang'anira kugwiritsa ntchito mphamvu, CT imagwira ntchito yofunika kwambiri m'makina amagetsi amakono. Kutha kwake kuwerenga magetsi molondola komanso magwiridwe antchito odalirika kumapangitsa kuti ikhale gawo lofunikira kwambiri m'mafakitale ndi ntchito zosiyanasiyana.
