Which formula is correct?

The correct formula for calculating Phase-to-Neutral Voltage in a three-phase power system is Phase-

to-Neutral Voltage = Phase-to-Phase Voltage / 1.732. This formula applies to balanced three-phase

systems, where 1.732 (or √3) represents the relationship between line-to-line and line-to-neutral

voltages.

Detailed Explanation:

In three-phase systems, Phase-to-Phase Voltage is higher than Phase-to-Neutral Voltage by a factor

of √3. Dividing the phase-to-phase voltage by 1.732 gives the phase-to-neutral voltage, which is

critical for understanding power distribution in three-phase electrical systems commonly found in

data centers.
