  • Abstract
    The paper makes a comparison of permissible temperature rises for short-time and intermittent ratings and permissible rises for continuous ratings. It suggests methods for the application of short-time ratings to various typical classes of intermittent load conditions and presents for each of these classes ways and means for properly co-ordinating the ratings of the major devices (motors and generators) and the ratings of the auxiliary devices and conductors.
