Summary:PURPOSE: A detecting apparatus, and system and method early alleviate influence due to the generation of the power outage the precision of AC power loss by providing the warning. CONSTITUTION: A power supply(106) receives a message the AC power waveform. The electric power wave comprises the predetermined cycle coping with the predetermined frequency. By rectifying the electric power wave rectifier is created the rectified electric power wave. The analog digital converter samples the rectified electric power wave as described above. The initialization module initializes the saved threshold amplitude corresponding to the point known as within the predetermined cycle as described above.
