Phase sequence or often called phase rotation of 3 phase supply system is defined as the sequence or order in which voltage in R, Y and B phase is attains their maximum value. Normally the phase sequence is RYB. This means, first R phase voltage attains its peak value followed by Y and B phases. This phase sequence is determined by this indicator.
