Here's a question for the power engineers in the group.
I measured the following phase voltages for the 3-phase power lines feeding
a breaker box:
phase to phase (all three phases) = 240V
phase to neutral (2 of 3 phases) = 120V
phase to neutral (1 of 3 phases) = 208V
Normally you would expect the phase to phase voltages to measure 208V and
the phase to neutral voltages to measure 120V for a Y-connected transformer.
What kind of power transformer configuration would provide these phase
voltages?
Thanks in advance to anyone who can shed some light on this,
Richard Meyette
