Renumber Star Buses...
This option allows renumbering the star buses of three-winding transformers to user-specified
values. This is done via a text file that is loaded with the new designations. The format of the
text file is the following:
Primary bus, Secondary bus, Tertiary bus, circuit, new star bus number, new star bus name
Either the bus number or name_nominal kV (secondary key field) combination may be used to
identify the buses. Each bus may be identified using either method even for the same threewinding
transformer. Use double slashes (//) to indicate a comment in the file. Any text past the
double slashes will be ignored. The file may be either space or comma delimited. If the tertiary
bus does not exist, this entry should be either a 0 or empty string enclosed in double quotes. If
the new star bus number already exists and is the star bus of another three-winding transformer,
the star bus number of the other three-winding transformer will be reassigned and the current
transformer will take the specified number. If the specified new star bus number already exists
and is not taken by another star bus, the three-winding transformer will not be updated with the
specified new star bus number.
