The invention provides a method for judging the wiring correctness of an electric energy meter under the condition of no load, which belongs to the technical field of on-site inspection and acceptanceof electric energy metering devices. The method comprises the following steps: S1, switching on a reactive power compensation capacitor bank, and measuring the secondary current of an electric energymeter, wherein the magnitude of current should conform to the requirements of the regulation; S2, recording the voltages of the phases A, B and C as Ua, Ub and Uc respectively, recording the line voltage combinations under the condition of wiring along the phase sequence as Uab and Ucb, recording a first phase current as Ia, and recording a second phase current as Ic; S3, using a volt-ampere phase meter to measure the voltage and the current of the wiring of the electric energy meter and the phase between the voltage and the current in turn, and recording corresponding data; and S4, determining whether the wiring of the electric energy meter is correct according to the recorded data. The problem that the wiring of an electric energy meter cannot be measured under the condition of no loadcan be solved. The work efficiency of on-site acceptance can be improved.
