Definitions:

Three-Phase Voltages

Voltages derived from a three-phase power system, characterized by three alternating currents that differ in phase by one-third of a cycle.

Out Of Phase

The condition in which two components do not reach their positive or negative peaks at the same time.

Three-Phase Connection

A type of electrical connection typically used for power transmission that involves three alternating currents of the same frequency, each 120 degrees out of phase with the others.

Line Voltage

The voltage measured between any two lines in a multi-phase electrical power system, often higher than the voltage from any one line to neutral.
