three phase step down transformer 280v to 220v 500kva

A three-phase autotransformer is defined as a special transformer that does not require insulation at the primary and secondary levels. Simply put, it means that its winding primary and secondary are on the same winding, that is, a transformer with only one winding, that is, it is a special transformer with output and input sharing a set of coils.
Coil Number:

Introduction
Three-phase autotransformers are used in applications where primary and secondary isolation is not required, and have the advantages of small size, few consumables and high efficiency. Fundamentally, it is to eliminate a coil to reduce costs, and has the function of ordinary transformers, that is, to increase or lower circuit voltage, isolation and reduce impedance.
 
 
In addition, it can be made into an AC voltage regulator to flexibly change the output voltage for laboratory use.
