Provided is an electronic electricity meter. Since inductive power from a magnetic field surrounding a transmission line is generated using a current transformer, and the inductive power is stored to be used as a driving power source for the electricity meter, the present invention can prevent power from being consumed by the electricity meter in an unloaded state. In addition, the present invention can protect the electricity meter from a surge voltage, lightening, or the like by insulating the transmission line and internal components from each other. In addition, when a power cut-off instruction is received from the electrical energy measurement server, the present invention can cut off power supply to a load by turning off a switch in a power source cut-off unit installed on the transmission line, and when a power supply instruction is received from the server, can remotely control power supply to the load.
