What is defined as the voltage between any phase and neutral?

The voltage between any phase and neutral refers specifically to phase voltage. In a three-phase electrical system, each phase carries an alternating current and is at a specific voltage level relative to a neutral point. The neutral serves as a common return path for the currents and provides a reference point for voltage measurement. Phase voltage is crucial in understanding the behavior of loads connected in a three-phase system and is essential for calculating the power and performance of electrical equipment.

Line voltage, on the other hand, represents the voltage between two phases in a three-phase system. Reactive power and apparent power do not refer to voltage measurements but rather to different aspects of electrical power in AC circuits. Reactive power deals with the power stored and released by inductors and capacitors, while apparent power is a measure of the total power in an AC circuit, combining both real power (which performs work) and reactive power. Understanding the distinction between these terms enhances comprehension of electric power systems and their operation.
