Mafuta oteteza kutentha mu transformer nthawi zina amatha kukhudzana ndi mpweya. Zitha kuchitika panthawi yotsegula malo opanda kanthu kapena chifukwa cha kutuluka kwa madzi m'matanki amafuta kapena m'mizere ya mapaipi ogwirizana nawo. Chifukwa cha zimenezi, kusintha kwa okosijeni mu mafuta a transformer kumachitika, komwe kumawonjezereka chifukwa cha kutentha ndi kupezeka kwa zinthu monga chitsulo, mkuwa ndi zinthu zachitsulo zosungunuka mu mafuta a transformer.

kusintha kwa mtundu wa solvent yotulutsidwa pogwiritsa ntchito methyl lalanje kapena phenolphthalein indicator motsatana, kapena kudziwa pH ya solvent yotulutsidwa pogwiritsa ntchito acidity meter kuti mudziwe ngati pali soluble acid ndi alkali mu solvent yotulutsidwayo.

Makina athu ali ndi ubwino wotsatira:
