Select an autotransformer suited to both the line voltage and the power
requirements of the system.
Proceed with the selection as follows:
⇒ Determine the rating group using the required rated line voltage range
in the diagram "Classification of the three-phase alternating current
autotransformers and then locate the transformer ratio "i".
Calculate the actual transformer output voltage using the rated line
⇒
voltage and the transformation ratio "i".
⇒ Check the drive data. The output voltage of the transformer has an
effect on the drive data.
Select a three-phase autotransformer corresponding to the required
⇒
connected load.
