The invention discloses an intelligent indication method and indicator for faults of a low-voltage metering box, and the method comprises the steps: initial data collection: enabling a low-voltage metering box to be connected with a power grid and a simulation load in a simulation experiment, simulating fault inducements until the low-voltage metering box breaks down, recording the fault type, corresponding abnormal parameters and cause conditions, and obtaining an inducement table; analysis of inducements: collecting fault parameters of the low-voltage metering box with faults, and sorting fault types and inducements according to the matching degree by combining an inducement table; and inducement indication: acquiring an inducement sequence of the low-voltage metering boxes with faults in the designated area, checking the inducement condition similarity of the low-voltage metering boxes without faults, and indicating the low-voltage metering boxes with the inducement conditions higher than a threshold value
