Trouble shooting a three phase delta 240v bank.
Trouble shooting a three phase delta 240v bank.
(OP)
On a three phase delta 240v bank consisting of 3 single phase transformers, I am getting a phase to phase voltage of 120v,120v,240v. The problem is a crossed primary supply with two phases at the same potential. Can anyone explain to me how this works. Thank you

Phase B to gnd 120 and Phase C to gnd 208 volts. Your reading indicate one of the phase fuses is blown.

you have half voltage across P1-P2 and P2-P3. You have full
voltage across P1-P3.
