What is the phase to ground voltage in a 4160 four wire system?

Explanation:
In a three-phase wye system, the voltage from any one phase to neutral (or ground, since the neutral is grounded in a four-wire setup) is the line voltage divided by the square root of 3. With a line-to-line (phase-to-phase) voltage of 4160 V, the phase-to-neutral voltage is 4160 / √3 ≈ 2400 V. Since the neutral is grounded in a four-wire system, the phase-to-ground voltage is the same as the phase-to-neutral voltage, about 2400 V. The other numbers would correspond to either the line-to-line voltage or aren’t the correct phase-to-ground value for this configuration.
