Substation Transformers are Equipment Container containers within Substations. They include two Equipment Containers: A high-side and a low-side transformer. These high-side and low-side containers normally include at least one piece of equipment associated with a Transformer.

Substation Transformers can be created, modified and deleted from the 'Transformers' window.
To manage a Substation Transformer, use the 'Insert' or 'Edit' context menu item accessible via clicking the right mouse button on an item within the treeview of Line Sections and Substations within the Application's main window. Using the 'Insert' menu item will cause a new Substation Transformer to be created and inserted immediately prior to the currently selected item.

Or, you can create a new Substation Transformer by utilizing the 'New' context menu item on the Substation in which you wish to add the Substation Transformer. Using the 'New' menu item will cause a new Substation Transformer to be created and appended to the end of the current list of known elements within the corresponding Substation.
