Transformer itagira aho ibogamiye ishingiye kubaministre

Muri gride ya 6-35KV ya AC yumuriro wamashanyarazi yigihugu cyanjye, hari ingingo zidafite aho zibogamiye zidafite aho zihuriye, zashizwe mumashanyarazi yo guhagarika arc, zirwanya cyane, kandi zidafite imbaraga nke.Muri sisitemu y'amashanyarazi (cyane cyane imiyoboro yo mumijyi itanga amashanyarazi hamwe ninsinga nkumurongo wingenzi wohereza), imiyoboro yubutaka nini nini, ishobora gutuma habaho kubaho "intermittent" arc ground overvoltage ifite ibihe byihariye "bikomeye", bikaviramo gutera Gukoresha uburyo butagira aho bubogamiye bwo guhuza imbaraga kugirango habeho kubyara ingufu zirenze urugero bikora umuyoboro usohora ingufu (charge) muri capacitance ya gride-to-ground, kandi ugatera imiyoboro irwanya imbaraga mukibazo, bigatuma ikosa ryikosa rifata. imiterere-yo kurwanya-ubushobozi, kugabanya no gutandukanya icyiciro cya fonction ya voltage igabanya igipimo cyo kongera gutwikwa nyuma yikigezweho aho ikosa ryambukiranya zeru kandi ikavunika imiterere "ikomeye" ya arc overvoltage, kuburyo ingufu zirenze urugero muri 2.6 ibihe bya voltage yicyiciro, kandi mugihe kimwe cyemeza kurinda cyane-gukingira ikosa ryibikoresho Ibikoresho bigena neza kandi bigabanya amakosa yibanze nayisumbuye ya federasiyo, bityo bikarinda neza imikorere isanzwe ya sisitemu.
