Reset" buttons
The condition for any source to be enabled in tie-point mode is to set the settings Vt line
enable and Vt load enable as TRUE and the respective source enable push buttons need to
be activated as explained above. The configuration logic for source selection is shown in
Figure 48.

Once the line side source is selected the phases of the respective source is identified by
giving the number of voltage transformers connected to the respective source.
In case of sectionalizer mode, the Vt config line setting is selected with number of voltage
transformers connected. If the Vt config line is "1" or "2",the Vt line phase setting is
selected as the phase to which the voltage transformers is connected. The Vt line enable
should be TRUE to consider the settings Vt config line and Vt line phase.
