1. A method for power theft detection, the method comprising:
receiving, by a control system, telemetry data from a transformer adjacent to a customer premise and a meter at the customer premise;
storing, by the control system, the telemetry data in a memory;
calculating, by the control system and using the telemetry data, a change in impedance in an electric line segment between the transformer and the meter; and
determining, by the control system, whether the change in the impedance in the electric line segment is anomalous, wherein determining whether the change in the impedance in the electric line segment is anomalous includes:
retrieving, by the control system and from the memory, a plurality of previously calculated changes in the impedance in the electric line segment; and
determining, using a machine learning model and the plurality of previously calculated changes in the impedance in the electric line segment, whether the change in the impedance in the electric line segment is anomalous.
