The two commonly used methods are the rotating phase-sequence meter or the static phase-sequence indicator. In cases where multiple cables need to be connected parallelly in the same phase; ensuring that the same current goes through all cables is possible by the right phase sequence and the correct arrangement of the cables, given the magnetic field interaction and impedances between the cables. It explains how to determine phase sequence using phasor diagrams and demonstrates the effects through a calculation example. It dictates the order in which the phases (typically labelled A, B, and C) energize a circuit.
