A 3 phase to 2 phase transformer??? If you needed 2 phases, why wouldn't you simply use 2 phases of the 3 phases that were available?
I've heard that you can tell when you're in a DC elevator. They jolt when they take off.

Open delta was used when the user only need a three phase source for small loads. Now, 120/208, "Y" configuration is common! Also, very common in apartment buildings, even if they don't have an elevator!
More later!
