The disclosure relates to a method and apparatus for power-off monitoring of an external protective device (EPD). The power-off monitoring apparatus monitors the abnormal power-off of an EPD, and includes a power-taking line, a power-taking switch-on module and a warning module. The power-taking line connects the power-off monitoring apparatus to a dedicated power outlet which is not connected to the power supply circuit of EPD; The power-taking switch-on module monitors abnormal EPD power off, and switches to connect with the power-taking line when abnormal power-off is detected. The warning module is used to send warning information when the power-off monitoring apparatus is launched. Through the mutually exclusive power supply design, the apparatus can switch to connect the dedicated power outlet to launch when the EPD is abnormally powered off. thu effectively preventing the safety problems caused by powering off the EPD.
