there was actually a similar thing on another thing we graded, where a three-phase system had a *phase* voltage of 208 V
(for those confused: 208 V is the *line* voltage that corresponds to the extremely common *phase* voltage of 120 V. 208 V phase voltage is just plain unheard of)
(for those confused: 13.5 kV is not a voltage you ever see in the real world, but 13.8 kV is extremely common as one of the standard distribution voltages)
