A three-phase autotransformer. The device is built from a three single-phase autotransformers, joined together. The voltage regulation is accomplished through a common mechanical shaft, with a manual “steering wheel” at the top.
The colours: red, yellow and blue denote the phases.
The device is around 1 m tall.
