Contributions concerning the short-circuited mobile coil transformers

Iulian Baciu

Abstract


In this paper there are analyzed the two types of mobile coil transformers, the short-circuited mobile coil transformer and the transformer with axial moving coil. The voltage adjustment features are analyzed using the two devices. Also the author presents equivalent circuit and its implications regarding the functioning of the two types of transformers. There are examined the factors affecting the "0" voltage value and some solutions are proposed in order to reduce this value. A demonstration model is presented related to the solutions presented early in the paper
