pypowsybl.network.Network.get_3_windings_transformers

Network.get_3_windings_transformers(all_attributes=False, attributes=None, **kwargs)[source]

Get a dataframe of 3 windings transformers.

Parameters:

  • all_attributes (bool) – flag for including all attributes in the dataframe, default is false

  • attributes (List[str] | None) – attributes to include in the dataframe. The 2 parameters are mutually exclusive. If no parameter is specified, the dataframe will include the default attributes.

  • kwargs (Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str]) – the data to be selected, as named arguments.

Returns:

A dataframe of 3 windings transformers.

Return type:

DataFrame
