The invention relates to a microcomputer relay protection device power cut length recording method, system and device, when the microcomputer relay protection device is not powered down, the time information is generated according to the current time and written into the memory, and the storage of time information is stopped when the microcomputer relay protection device is powered down. When the microcomputer relay protection device re-power, the stored time information is read, and according to the time information the event recording information can be read and the recording device has normal output. The writing time information is stopped when the microcomputer relay protection device is powered down, and the stored time information is read after power-on again, and event recording information is generated, which can accurately record the power-off time of the microcomputer relay protection device, and provides the reference for the fault analysis to improve the convenience of the analysis of the cause of
