Nahoana ny transformer vao tafapetraka na nohavaozina no mandalo fitsapana fanakatonana misy fiantraikany alohan’ny hampiasana azy?

Ny fanapahana ny transformer tsy misy entana mandeha ao amin’ny grid dia hiteraka overvoltage miasa. Ao amin’ny rafitra fanondrahana kely amin’izao fotoana izao, ny halehiben’ny antsoina hoe overvoltage dia mety hahatratra 3 ka hatramin’ny 4 heny amin’ny volavolan-tsarin’ny dingana; Ao amin’ny rafitra fototra lehibe iray, ny haben’ny overvoltage miasa dia mety hahatratra in-3 avo heny amin’ny volavolan-tsolika. Noho izany, mba hitsapana raha mahatanty ny insulation ny transformer sy ny overvoltage miasa mandritra ny fandidiana, dia ilaina ny manao fitsapana fanakatonana impulse maromaro alohan’ny hampiasana ny transformer. Ankoatr’izay, rehefa ampiasaina ny mpanova tsy misy entana, dia hipoitra ny rivo-doza mampientam-po, ary mety hahatratra 6 ka hatramin’ny in-8 ny sandany amin’izao fotoana izao. Koa satria ny firongatry ny firongatry ny firongatry dia hiteraka hery electromotive lehibe, ny fiatraikany fanakatonana fitsapana dia mbola fepetra mahomby mba handinika raha ny mekanika hery ny mpanova sy ny relay fiarovana dia tsy miasa.
