A kuma, wadannan batutu zasu iya kura:

Na farko, idan kuma dry-type transformers suna da kyau a kula da ruwa, amma har abada tsarin bautensu ya sa su kasance masu yanke ruwa – musamman transformers da sufuren China, waɗanda yana da wuyan insulation mafi karanci. Don haka, don kyau mai zurfi, dry-type transformers dole ne su aiki cikin mahali da ke da humidity mai yankiwa fiye da 70%. Wane zama mai tsoron amfanin ya kasance ban mamaki don karyawa ruwa. Idan alamar insulation ta kara karanci da 1000 Ω/V (na operating voltage), yana nuna cewa ruwa ta shiga sosai, kuma aiki na gyara-gyara dole ne a kashe.

Na biyu, dry-type transformers da ake amfani da su don maganiyar voltage a cikin power stations su fara dari da oil-immersed transformers: babu izinin aki aiki tare da low-voltage side open-circuited. Zaman lauya mai darajar low-voltage za a iya bude insulation na transformer ta hanyar transferred overvoltages – dole ne a sarrafa su ne da switching surges ko lightning strikes a gaban grid. Don kari daga wannan transferred overvoltages, dole ne a shigar da set na surge arresters (misali, Y5CS zinc oxide arresters) a gaban busbar na transformer.
