Method and device for determining high-voltage electricity stealing user

The invention discloses a method and equipment for determining a high-voltage electricity stealing user. The method comprises the following steps: receiving effective business data of a user; extracting an A-phase current absolute value and a C-phase current absolute value in a preset time period from the effective business data; for each user, calculating a first average value of A-phase current absolute values and a second average value of C-phase current absolute values in the preset time period; selecting a judgment model according to the first average value and the second average value; and determining the high-voltage electricity stealing user according to the judgment model. By mining the business data of the high-voltage user, the data characteristics of high-voltage electricity stealing are associated with the judgment model in a targeted manner, so that the high-voltage electricity stealing user can be quickly and accurately determined, the efficiency of investigating the electricity stealing behavi
