The invention provides a system and method for preventing electricity from being stolen. The system comprises a server, multiple coordinators, multiple mobile terminals, and multiple electricity meter units. Each electricity meter unit includes a first electricity meter and multiple second electricity meters. Each second electricity meter is used for calculating the amount of electricity consumed by each user at every interval with a preset period of time. The first electricity meters are used for calculating the amount of electricity that passes through a main line at every interval with a preset period of time. The server determines whether the amount of electricity consumed by the users is normal according to the amount of electricity and the historical amount of electricity consumed by each user, the sum of the amount of electricity consumed by the users, and the amount of electricity and the historical amount of electricity passing through the main line. If determining that the amount of electricity consumed by the users is abnormal, the server generates and sends a first fault-fixing dispatch list to a target mobile terminal which is the nearest to the first electricity meters. The system and method for preventing electricity from being stolen can acquire the amount of electricity consumed by each user in a remote and fast manner, and also can detect whether electricity is stolen or how serious line losses are.
