...Phase Voltage Monitoring Relay phase failure protective deivce Phase sequence protector principle Phase Sequence Protector Principle Under normal circumstances, the wiring order of the motor work is regulated. If for some reason, the phase sequence is disordered, the motor will not work properly or even be damaged. Phase sequence protection is to prevent such accidents from happening. Phase sequence protection can use phase
