NettetThe turn-to-turn SC (TTSC) fault is inherently self-exacerbating and for the TTSC of a stator winding there are lowest voltage and the highest current in the SC fault turns. Since the ohmic losses are directly proportional to the square of the current, the generated heat may damage insulation of the adjacent SC turns and the fault spreads to more turns.
