In the field calibration of the electric energy meter, data information such as on-line voltage, current and the like of the electric energy meter to be calibrated needs to be acquired, wherein current signals are extracted through a pincerlike current transformer.
The overall precision and the subentry precision of the existing electric energy meter need to be calibrated and calibrated, wherein the pincerlike current transformer needs to be calibrated in precision on the corresponding phase on the corresponding electric energy meter field calibrator, and calibrated correction data are stored in the electric energy meter field calibrator.
Therefore, the pincerlike current transformer needs to be applied to the specified phase of the specified electric energy meter field calibrator and cannot be replaced at will, otherwise, the measurement precision is affected.
In addition, after the actual current signal is less than 10% of the rated current of the used split core type current transformer, the test precision is greatly reduced. Therefore, the existing on-site check meter for each electric energy meter adopts more split core type current transformers with different measuring ranges, so that the split core type current transformers with the proper measuring ranges can be selected on site according to specific conditions.

4) when the three phases are unbalanced, the A, B, C three phases can not select the clamp-on current transformer with different measuring ranges respectively aiming at different currents.
5) When the used pincerlike current transformer is inconsistent with the electric energy meter field calibrator, the pincerlike current transformer is not easy to find, and the automatic prompt function is not provided.
