Phase Sequence

Phase sequence refers to the correct order in which alternating current (AC) power flows through three-phase systems, typically used in industrial and large-scale electrical setups. Think of it like a coordinated dance where each "partner" (phase) moves in a specific order to ensure smooth operation. If the sequence is reversed, equipment can run backwards, which may cause damage or malfunctions. Maintaining the proper phase sequence ensures consistent power delivery, efficient performance, and the safety of electrical devices and machinery. Proper identification and correction of phase sequence are essential for the reliable operation of three-phase systems.
