In ungrounded circuits, what is the voltage measurement taken between a given conductor and any other conductor called?

The term that refers to the voltage measurement taken between a given conductor and any other conductor in ungrounded circuits is known as line-to-line voltage. This is particularly relevant in three-phase systems where the voltages between each pair of conductors are important for understanding the operation and safety of the electrical system.

Line-to-line voltage provides crucial information about the potential difference between two phases. This distinction is especially significant when determining load characteristics and ensuring proper equipment functionality in three-phase power systems.

In contrast, phase voltage typically refers to the voltage measured between a conductor and a neutral or ground reference in a grounded system, while voltage to ground rates the potential from a conductor to ground. System voltage will denote the total operational voltage of a power system but does not specifically indicate the measurement between two conductors. Hence, understanding the specific context of 'line-to-line voltage' is fundamental to accurately navigating electrical measurements in ungrounded circuits.
