Can someone explain the source and the value of a "wild leg". that is, one of the three phases has a higher voltage than the other two, in 3 Ph service?
I recently read about the use of "open Delta" setup, which uses only 2 transformers (for reason of economy to the utility) to supply the 3 legs, but according to the article, the voltages in that system are balanced.
Where does the higher voltage come from? A higher tap on one transformer? Why would one want one leg to be "hotter?
