What is the phase to neutral voltage of a 23 kV system?

To determine the phase-to-neutral voltage in a 23 kV system, it's important to understand the relationship between line-to-line voltage and phase-to-neutral voltage in a three-phase system. The line-to-line voltage is the voltage measured between any two of the three phases, while the phase-to-neutral voltage is the voltage measured from any one phase to the neutral point.

For a three-phase system, the relationship is defined by the formula:

Phase-to-Neutral Voltage = Line-to-Line Voltage / √3

In this case, the line-to-line voltage is 23 kV. To find the phase-to-neutral voltage, we perform the following calculation:

Phase-to-Neutral Voltage = 23,000 V / √3

≈ 23,000 V / 1.732

≈ 13,274 V

When expressed in kilovolts, this results in approximately 13.2 kV. Therefore, the phase-to-neutral voltage of a 23 kV system is indeed around 13.2 kV.

This understanding is critical for working with electrical systems, as knowing the phase-to-neutral voltage helps linemen and electrical engineers design and implement safe and effective power distribution systems.
