In a system described as 7200/12470, what is the line-to-line voltage?

The two numbers in a notation like 7200/12470 represent the line-to-line voltages on the two sides of a transformer or system. The higher value corresponds to the high-voltage side, which is the line-to-line voltage for the system. So the line-to-line voltage is 12,470 V. If you ever relate this to phase voltage on a wye-connected side, the phase (line-to-neutral) voltage would be the line-to-line voltage divided by sqrt(3).
