Transformer Field Options Dialog

Transformer field display objects are used to show field values specific to transformers on onelines. Use Line Fields to show fields generic to transformers and transmission lines, such as the flow of power through the device.

This dialog can be opened by right-clicking on a transformer display field and choosing to open the Transformer Field Information Dialog while in run mode. If in edit mode this dialog will be opened simply by right-clicking on a transformer display field.

The transformer field options dialog is used to view and modify the parameters associated with transformer-specific fields.
