Figure 141 shows the Zero-voltage motor open-phase protection circuit diagram. When running motor occurs single-phase outage, the protection device can automatically cut off power to avoid motor occuring open-phase running. Working principle: when normal operation, the potential of the three-phase power balance point E is zero.
