Discussion at Pacific Coast convention: The 60-cycle distribution system of the Commonwealth edison company

P. P. Ashworth: From a consideration of the line diagrams in this paper and in other papers presented, it would seem advisable for the Institute to adopt a set of standard symbols to be used by authors in these diagrams. This would make for clarity and simplicity. In Fig. 15 of Mr. Kelley's paper the key to symbols is not given, thus detracting materially from the value of the diagram.
