What does phase voltage measure in a balanced 3 phase system?

Phase voltage in a balanced three-phase system measures the voltage across any single phase. In this type of system, each phase operates independently and is separated by 120 degrees in terms of phase angle. Consequently, the phase voltage refers specifically to the voltage measured from one phase conductor to the neutral point.

This measurement is critical for understanding how individual loads operate within a balanced three-phase system, as it allows for accurate assessments of power distribution and electrical characteristics for each phase.

Choosing this option aligns with the fundamental principles of three-phase systems used in electrical engineering and HVAC applications, where understanding phase relationships and voltages plays a vital role in system design and analysis.
