Corrosion of Metals subject to moisture is analogous to the destructive power of the atomic bomb to ships at sea. Whereas the atomic bomb destroys all material in a limited space, corrosion is world wide. Prevention of corrosion was pioneered by the men who are our corrosion engineers of today. Cathodic protection equipment was developed through the combined efforts of corrosion engineers and manufacturers of electrical equipment.
Cathodic protection equipment may be divided into several groups: Wind chargers; engine generator sets, and rectifiers of various types such as air-cooled, fan-cooled, and oil-immersed.
Wind chargers are used primarily in isolated places inaccessible to electric power or natural gas. As their name implies, wind charges depend upon the wind for power, and cathodic protection can only be obtained when the wind is blowing. This equipment has moving parts which require maintenance. A few late model wind chargers employ a storage device to...
