The accident or equipment damage occurs because the power phase sequence is reversed and reversed. Such as elevators, central air conditioners, cranes, motors, etc. If the phase sequence of the power supply is faulty after maintenance, an accident will occur, and the phase sequence protector must be connected to the control loop to ensure that the phase sequence is correct. Air-conditioning compressors also use phase sequence protectors to ensure that the compressor does not reverse after repair.
