Hi all
To my email above I should have added:
With this understanding of the network topology, you only need a  
single transformer nameplate or busbar label to confirm the voltage of  
a feeder for its entire length. If you can observe the busbar and  
switching layout at the source substation you will be able to confirm  
the voltage of the sister feeders too.
