User interface > Edit components > Special, Change voltage

The nominal voltage of some (probably connected) nodes can be changed collectively.

Select the relevant nodes.

Choose Start | Edit | Special | Change voltage.

Enter the new nominal voltage.

In addition to the nominal voltage of the selected nodes, adjacent objects are also changed slightly.

They are:

•rated voltage and type name (becomes blank) of machines

•rated voltage and tap size and type name (becomes empty) and voltage control of transformers.

Cables, lines, links and reactance coils that become between nodes with different nominal voltage are opened.

The idea is to manually transfer them to a node with the new nominal voltage, via Start, Edit, Topological, Transfer and then close the switch.

And list of the changed objects will be displayed afterwards.
