A study of short-time ratings and their application to intermittent duty cycles

摘要

P. L. Alger (General Electric Company, Schenectady, N. Y.): It is very desirable to use a simple and flexible method of rating electrical apparatus, that will tell the user its output limitations in as few words or symbols as possible. All that the user really needs to know about the capacity of his apparatus is that it has adequate power for his maximum peak loads, and that it will have satisfactory life under his actual load conditions. Only two numbers should be needed to define these two output limits, corresponding to the momentary and the continuous ratings.
