The invention discloses a system and method for detecting surge immunity of an electric energy meter. A combination waveform generator can output surges with preset parameters to a tested electric energy meter, and a meter calibration device detects the metering error of the electric energy meter. Due to the fact that the meter calibration device detects the metering error of the tested electric energy meter under the condition of simulation of practical using conditions of the tested electric energy meter, at the moment, the combination waveform generator inputs the surges with the preset parameters to a voltage circuit input end of the tested electric meter, therefore the metering error of the tested electric meter influenced by the surge conditions during the metering process can be detected, and the metering error is used as the first metering error. After the combination waveform generator is closed, detection is conducted on the tested electric meter, the metering error of the tested electric meter under the condition free of disturbance can be obtained, and the metering error is used as the second metering error. Calculation is conducted on the first metering error and the second metering error, and the surge immunity of the tested electric meter during the metering process can be obtained.
