Is line voltage the amount measured between any two line conductors of a balanced 3-phase system?

In a balanced three-phase system, line voltage is indeed defined as the voltage measured between any two line conductors. This is a key principle in understanding three-phase power systems. In such systems, there are three conductors, each carrying alternating current and separated by 120 degrees in terms of phase angle.

When measuring line voltage, you are assessing the potential difference between two of these conductors. This measurement is crucial for determining the distribution of power and ensuring that the system operates efficiently. The relationship between line voltage and phase voltage further helps in calculating power requirements and load distributions.

It’s important to note that this concept applies specifically to balanced three-phase systems and does not pertain to single-phase systems or unbalanced systems because those different setups involve distinct voltage measurements. Therefore, recognizing the definition of line voltage in the context of a balanced three-phase system confirms the correctness of the answer.
