A method, system, and apparatus for detecting electricity theft are disclosed. Electricity theft is the practice of stealing electrical power from a provider. Violators are not charged for the total number of kilowatt-hours actually used, causing lost revenue for both utility companies and retail electricity providers. The method, system, and apparatus may comprise providing power to a plurality of end user destinations from one power source, selecting one destination for testing, and switching off all of the end user destinations except for the selected destination. The method, system, and apparatus may further comprise sensing the current from the power source, sensing the current returning from the selected destination, and determining the difference. The presence of electricity theft can be determined if the current entering the system is not the same as the current returning from the system.

The invention relates to an adjustable input scheme specially used for detecting the erroneous wire connection of an outdoor electric energy meter. According to the scheme, a signal generator is configured to input a specific signal into the electric energy meter to be detected to detect whether a corresponding relation between a power consumer and the electric energy meter is correct. The scheme, based on a related patent of the Qingdao topscomm communication co., Ltd., realizes an optimized signal input effect by using multipoint injection and feedback control. A device for detecting the erroneous wire connection of an outdoor electric energy meter confirms the matching between the electric energy meter and the power consumer by inputting the specific signal into the electric energy meter to be detected, transmitting the specific signal into space via a power line from the air switch, the electric appliances or the like of the power consumer, and then receiving the specific signal wirelessly. The scheme realizes signal input under complicated environment, suppresses the influence of a reverse signal, and greatly improves the detection accuracy of erroneous wire connection.
