Print on Demand. This book chronicles the development of the concept that the ratio of transformation and of the phase relations in a transformer remain constant for constant secondary impedance and are little affected by varying voltage or moderate variation in frequency. It discusses the complicated apparatus and techniques used in transformer measurements and presents methods for determining the ratio of transformation and phase relations. Using a differential dynamometer voltmeter, the detailed explanations allow the reader to determine a transformer's ratio and its phase angle with respect to current for different conditions. The author also elucidates the influence of wave form upon the ratio and phase relations of transformers to provide a practical guide for readers seeking to optimize the performance of transformer-powered equipment. The depth of analysis and the rigor of the methodology make this book valuable for electrical engineers, power system designers, and transformer manufacturers. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book.…

The ratio Of E, to E, is known as the ratio Of a potential trans former, and in general it differs appreciably from the ratio of E,' to E,' which is the ratio Of primary to secondary turns. The phase-angle between E, and E, reversed is the angle which it is proposed to measure. This may be either positive or negative.
If no current be taken from the secondary, E, becomes identical with E,' N, I becomes identical with N, M I r, becomes smaller and farther from E,' in phase; the ratio is more nearly the ratio of turns; the secondary emf. Is in advance of the primary. As the secondary current is increased the Ohmic drop in the sec ondary increases and E decreases; I, must increase to maintain M I r, increases and comes more nearly into phase with E,' hence E, must be increased to maintain the same magnetic conditions, or if E, be maintained constant the flux decreases and E, suffers further contraction, so that the ratio is increased; as, will in general increase and the phase angle will approach zero and finally become negative.
