The problem of the research's urgency of modes and processes of drying the humidified isolation of electric machines of a rolling stock's windings was examined. The factors rendering essential negative influence on the electric durability of winding's isolation, were given and the primary goals of its reliability's maintenance were determined. Both the physical and chemical processes occurring in the firm body's volume (in windings of poles, anchors, cables), and on a surface, directly exposed to influence of environmental excited environment were described While in service an electric rolling stock isolation of windings of traction and auxiliary electric machines and electric devices is humidified, that results in sharp reduction of electric durability and demands realization of drynng. New alternative principles, methods, ways and means on drying the humidified isolation of the traction electric motor, based on use of a longitude-faltering way of electrocalorifious installation control with a descending level of power capacity for each of the subsequent cycles of the moisture's evaporation from isolation of traction electric machines windings, were offered. Faltering principles of processes control of drying the humidified isolation will allow receiving not only effect from the savings of energy, but also will provide high quality indicators at use of various methods of drying.
