The bus-list file is a text file with a bus name and nominal kV on each line. A sample file with four bus names is shown below:
'ARKANSAS', 33
'CLAYTOR', 132
'DOT BUS', 13.8
'FLORIDA', 33
Each bus name must be enclosed by single quotes or double quotes depending on the string-delimiter option you selected in the Network tab of the File | Preferences dialog box.
