Phase sequence, or phase rotation, is the order in which voltages in a three-phase electrical system reach their peak values (e.g., R-Y-B or R-B-Y), crucial for determining the rotation direction of motors and ensuring proper operation of equipment like transformers. A standard Positive Sequence (RYB) provides clockwise rotation, while swapping any two phases creates a Negative Sequence (RBY), reversing motor direction, which is essential for industrial applications and safety
