Abstract :
Class F insulation materials have usually been operated at Class B temperatures since their introduction in the early 1970s. Extensive testing and service experience appears to show that there is no reason for this reluctance to fully utilize the capability of the insulation. Experience with the latest types of generators indicates that perhaps this caution is still justified
