Three-phase auto-transformers | Choosing the right transformer
There are 5 main types of technology for transformers. Voltage transformer The voltage transformer makes it possible to modify the voltage and current delivered by an alternative electrical source while maintaining the same frequency. This transformation is carried out efficiently. Three-phase transformer The three-phase transformer allows the transformation of the voltage and current of three phases at the same time. This means you don’t have to use...
