Discussion on “theoretical investigation of electric transmission systems under short-circuit conditions,” (Gross), New York, January 8, 1915. (see proceedings for January, 1915)

Henry G. Stott: Perhaps a little account of the origin of this paper might be of interest. We were confronted by the problem of providing for a station which would ultimately contain seven 30,000-kw. units, and at the same time trying to avoid the results of six 30,000-kw. units in short circuits. First of all, we were very anxious about protecting the generator from short circuits. After a little investigation of the whole problem, it turned out that our efforts should be directed towards the feeders and busbars and not towards the generator, as the generator, with its relatively high reactance and modern construction, seemed to be pretty well able to take care of itself. The problem, then, of saving the feeders from what might happen, as we went further along in the investigation, became rather complex.
