<p>The invention relates to an angle displacement apparatus. According to the invention, the apparatus consists of a group of transformers () comprising three single-phase transformers (), two of them being supplied with adjustable voltage by means of two autotransformers () and the diagram of connections between the primary and secondary windings of the three single-phase transformers () is changed by a 12-point multiple switch () which allows phase-shift angles adjustable in steps of 30° to be obtained.</p> |
