The invention relates to a high-performance current transformer intelligent analyzer, which is applied to a saturation characteristic test for a transient state current transformer, direct tests for a sleeve current transformer and a current transformer in GIS and all parameter tests for all conventional transformers, and belongs to the technical field of current transformer test instruments. During voltage current characteristic tests for the transient state current transformer and a conventional high saturation characteristic transformer, because only the output frequency needs to be changed during the tests, the intelligent analyzer can perform the test on the transient state current transformer of which the saturation voltage is 15,000 kilovolts when the maximum amplitude value is 120 volts, and change the blank that at present no domestic equipment performs test on a transient sate winding; besides, the instrument output test voltage is low, which cannot cause potential safety hazards to the equipment and the personal safety; and because a booster transformer (generally, the weight of a transformer is tens of kilograms) for boosting is not needed, the weight of equipment to be tested is greatly reduced.
