I have not worked much with three phase systems and have heard many conflicting answers about their characteristics.
1) true or false, high leg deltas are typically found in rural areas an are rare in urban areas.
2) the high leg to ground voltage is:
a. 208 v
b. 277 v
c. varies from one system to another
What characteristics of the connection method or primaries result in a high leg?
Do utilities typically have a maximum size single phase service? What im getting at is what if you have say a large apartment complex (no three phase loads) whose load requirements exceed that of a single phase service and a three phase delta with a high leg is what is available. Does this ever happen and if so what would typically be done in this situation? Thanks! ~Ethan
