The present invention provides a high-voltage electric energy metering device current transformer leakage current eliminating method. According to the method, the potential of the primary loop of a current transformer is made to be equal to the potential of the secondary loop of the current transformer, so that voltage between the primary loop and the secondary loop of the current transformer is zero, and therefore, leakage current can be eliminated; and a double-secondary winding two-stage voltage transformer is adopted to replace an ordinary voltage transformer in a high-voltage electric energy metering device. With the method of the invention adopted, voltage and current synchronous sampling can be carried out under a high-voltage equipotential state, and therefore, a voltage withstand requirement for the current transformer can be lowered, and cost for purchasing a high-voltage current transformer can be saved; and leakage current elimination of the high-voltage electric energy metering device can be achieved.
