On a 7200/12470 system, the 7200 is the:

In a 7200/12470 system, the 12,470 V is the line-to-line (line) voltage on the high side, and the 7,200 V is the voltage from each phase to the neutral (ground) on the lower side. In a wye-connected arrangement, phase-to-neutral voltage equals the line-to-line voltage divided by sqrt(3). Computing 12,470 V ÷ sqrt(3) ≈ 7,200 V shows that the 7.2 kV value is the phase-to-ground (phase-to-neutral) voltage. The line voltage is 12.47 kV, and the neutral potential is tied to ground, so the phase-to-ground voltage is the 7.2 kV figure.
