The invention relates to the technical field of power distribution maintenance, in particular to a power distribution low-voltage outgoing line electric leakage monitoring system and method. Firstly, data are collected, and a power utilization habit model is constructed for a user. And then determining a power failure moment and a current-day fluctuation event. Then, the interval time of power fluctuation after the current-day fluctuation event is predicted in the power utilization habit model based on the current-day fluctuation event, and the predicted time difference is calculated; and obtaining predicted time differences of all users, wherein the user with the shortest predicted time difference is determined to be an electric leakage user. According to the invention, when the load switch trips due to an electric leakage fault or a short-circuit fault, users possibly causing faults can be predicted, so that a reasonable power transmission sequence can be made when power supply is recovered, and inconvenien
