PTinowanzozivikanwa sevoltage transformer muindasitiri yemagetsi uye CT ndiro zita rakajairika reshanduko iripo muindasitiri yemagetsi.
Voltage transformer (PT): ndiyo midziyo yemagetsi inoshandura yakakwira voltage yesimba remagetsi kuita imwe yakaderera voltage (100V kana 100 / √ 3V).
Inogona kushandura (PT, VT) yakafanana neshanduro, iyo inoshandiswa kuchinja magetsi pamutsara.Nekudaro, chinangwa nei transformer ichishandura voltage ndeyekufambisa simba remagetsi.Hunhu hwakakura kwazvo, kazhinji mu kilovolt ampere kana megavolt ampere seyekuverenga unit.Icho chikonzero nei voltage transformer ichishandura voltage inonyanya kushandiswa kuyera mamita uye magetsi nemagetsi ekudzivirira relay, kuyera voltage, simba uye magetsi emagetsi emutsara, kana kuchengetedza midziyo yakakosha mumutsara kana mutsara wakundikana Naizvozvo, simba re voltage transformer idiki kwazvo, kazhinji ingori mashoma volt ampere, gumi nemaviri evolt ampere, uye iyo yakakwira haisi kupfuura chiuru chimwe chevolt ampere.
Current transformer (CT): ndiyo midziyo yemagetsi inoshandura iripo muhigh voltage system kana hombe iripo mu low voltage system kuita imwe diki diki ikozvino (5a kana 1a).
Chazvino transformer chiridzwa chinoshandura yakakura iripo muchikamu chepuraimari kuita diki ikozvino mudivi rechipiri zvinoenderana nemusimboti wemagetsi induction.Ikozvino transformer inoumbwa neyakavharwa core uye mhepo.Yayo yekutanga mhepo inotenderera ishoma kwazvo, uye yakabatana munhevedzano mudunhu inoda kuyera ikozvino.Nokudaro, inowanzova nezvose zvino inoyerera kuburikidza nemutsara, uye yechipiri inotenderera inotenderera yakawanda.Iyo yakabatanidzwa munhevedzano mune yekuyeresa chiridzwa uye kudzivirira redunhu.Kana shanduko yemazuva ano iri kushanda, dunhu rayo rechipiri rinogara rakavharwa, saka iyo impedance yemutsara wecoil yekuyera chiridzwa uye chekudzivirira chedunhu idiki kwazvo, uye mamiriro ekushanda emushanduri wezvino ari pedyo nepfupi pfupi.Ikozvino transformer inoshandura ikozvino yakakura kudivi rekutanga kuita diki ikozvino padivi rechipiri rekuyera, uye chikamu chechipiri hachigone kuvhurwa dunhu.
