A conventional electric energy calibrator-based dynamic performance tracing method is disclosed and comprises the following steps: (1) a standard device which is 0.01 grade in accuracy class in a steady state test signal condition is chosen; (2) 0.05 grade high precision three phase standard electric energy meter without any automatic measuring range switching function is chosen as a 0.05 grade conventional electric energy calibrator; (3) in the steady state test signal condition, the 0.01 grade standard device is used for subjecting the 0.05 grade conventional electric energy calibrator to conventional calibration, and that the 0.05 grade conventional electric energy calibrator meets requirements for steady state indexes is ensured; (4) a 0.1 grade electric energy meter dynamic performance measurement device which needs to be calibrated is chosen; (5) in a dynamic test signal condition, the 0.05 grade conventional electric energy calibrator is used for calibrating dynamic performanceaccuracy indexes of electric energy meter dynamic performance measurement devices which are 0.1 grade and less than 0.1 grade in accuracy class via electric energy comparison; (6) in the dynamic testsignal condition, the calibrated electric energy meter dynamic performance measurement devices are used for calibrating the dynamic performance accuracy indexes of a detected electric energy meter.
