Abstract :
To the Editor: Sections 121, 122, and 123 of the A.I.E.E. Proposed Test Code for Synchronous Machines gives a method of finding the voltage regulation and load field current of alternators. I should like to ask what features of the proposed A.I.E.E. method make it superior to the method referred to in textbooks by Lawrence (“Principles of Alternating Current Machinery”) as the “general method” and by Bryant and Johnson (“Alternating Current Machinery”) as “method A” which has a rational basis?
