It is entirely possible that the 440 volts is from a delta configured
transformer that is not ground referenced or is corner grounded.
Point is that one shouldn't assume that the transformer that is
supplying the current is Y configured.

It's only possible to determine how a three phase transformer is
connected visually. Ie by checking the connections.

You can make a very reliable determination with just a meter and knowing
how 3 phase AC works.
