A Three Phase Sequence Corrector is an electrical device used to detect and correct the phase sequence (rotation) of a three-phase power supply. Proper phase sequence is critical for the correct operation of three-phase motors and equipment. This device ensures that the phases are connected in the correct order (typically R-Y-B), preventing equipment damage and operational issues caused by incorrect phase rotation

A Single Phase Sequence Corrector is a device used to ensure the correct phase connection in systems where single-phase power is derived from a three-phase supply or where phase-sensitive equipment requires the correct polarity or phase reference. Though phase sequence is typically a concern in three-phase systems, single-phase sequence correctors are used to verify polarity and correct wiring in single-phase systems to prevent operational errors or damage.
