Then the error sources of the reaction type and electron type electric energy mete were analyzed and the theory analysis result through the concrete test have been proved. At last, the main conclusion has been drawn. When the induction type electric energy meter measures harmonics energy, the negative error characteristic appears. The higher the frequency of harmonics is, the greater the error is. The electron type electric energy meter can measure harmonics energy accurately in general cases. Except thermo-electrical conversion type electron type power meter, reaction type and electron type electric energy meter can measure direct current power.
