Modelling and analysis of transformer winding configuration for application to distribution network

The development of the multiphase transformation system can be traced back to the early 1950s of the twentieth century. [6] At that time, A general theoretical framework for phase transformation, facilitating the conversion of 'n' phases to 'm' phases in a 'k'-limbed transformer, was proposed. Further elaboration has been provided on the general theories of phase transformation techniques from single-phase to multiphase systems in [7]. This concept has been explored and applied in the development of specialized transformer winding configurations, specifically designed to facilitate nine-phase output at the secondary side of the transformer. By strategically designing the winding arrangement, the transformation process ensures that the desired number of phases is achieved, thereby enhancing the operational flexibility and reliability of the system.
