| Popis: | One of the most characteristic defects in the manufacture of transformers during mass production is the presence of short-circuited coils (SCCs) in windings. The advantages of a method for the control of this defect via measurements of the Q-factor in relation to industrially used analogous control methods based on measurements of inductivity or losses in a transformer is shown on the basis of a mathematical model and analytical studies. An experimental apparatus for the empirical testing of the main theoretical concepts is developed. |
