modelACACTransformer
AC AC transformer three phase balanced systems
Extends from Buildings.Electrical.AC.OnePhase.Conversion.ACACTransformer (AC AC transformer simplified equivalent circuit).
Information
Simple transformer model for three-phase balanced AC systems. The model does not include core and magnetic losses.
See model Buildings.Electrical.AC.OnePhase.Conversion.ACACTransformer for more information.
