Protection of electric equipment against corrosion

CORROSION OF VITAL PARTS of electric equipment presents a serious problem in many industries which manufacture or use chemicals, or in which corrosive gases, dusts, or liquids are a by-product of the process operations. It is also present in plants located near salt water, in mines, and even in steam-generating plants which use hogged fuel or coal. Corrosion of electric apparatus not only causes high maintenance and operating costs but presents a definite safety hazard.
