On the Sudden Short-Circuit Phenomena of a Single-Phase Alternator

Abstract

Many papers on theoretical studies of transient phenomena in a sudden short circuited alternator were published already, the important ones, so far as the authors knows, are Otake, Shimidzu and Ito, Biermanns and Boucherot, especially Otake's Solution-by an integral equation-is the most rigorously but too complex.
The following study starts from an assumption which may be probably acceptable-e∫ρpdθ-∫ρ1p1dθ_??_a constant (near unity), and results thus obtained these two circuit currents, i. e. exciting current and armature current, are mutUally different jπ/2 in their phases for for both transient terms and compared with those given by the above authors.
The case of an alternator with an automatic voltage regulator is also treated.
