Two Winding Transformer

Model of a two winding transformer. It is assumed, that node A is the node with higher voltage.

Attributes, Units and Remarks

Type Model

All impedances and admittances are given with respect to the higher voltage side. As obvious, the parameter can be used in T- as in 𝜋-equivalent circuit representations.

Standard Two Winding Transformer Types

Following there are some standard two winding transformer types with their source. A csv file containing the types listed below can be found here <https://github.com/ie3-institute/PowerSystemDataModel/tree/dev/input/StandardAssetTypes>. This file can be used directly for any simulation with simona. The transformers which source is simBench are from here <https://simbench.de/en/download/datasets/>.
