Current transformer electronic compensator

The utility model is used for enhancing the measuring precision of a current transformer, which belongs to the technical field of electric signal measurement. The utility model is composed of a double-pole current transformer and an active zero magnetic flux current transformer. The current transformer used in an electric power system at present has low measuring precision and is unable to meet the accuracy requirement of the electric energy measurement. Traditional processes for error compensation, such as the replacement of core materials or the appendix of a compensation apparatus in the transformer, both have the defects of difficult manufacture and high cost. The utility model can be connected in the secondary circuit of the transformer needed to compensate indoors, the installation, the debugging and the maintenance are all convenient, and the utility model is particularly suitable for raising the measuring precision of the current transformer running in the system.
