The utility model relates to an intelligent transformer substation current transformer polarity testing device. The intelligent transformer substation current transformer polarity testing device comprises a signal decoding and acquisition module, a data caching and recording module, a human-machine interaction module, a low-pass digital filtering module, a polarity discrimination module and a polarity result and waveform display module. The polarity of a current transformer can be tested through a merging unit; the intelligent transformer substation current transformer polarity testing device is adaptive to polarity test of protection windings and measurement windings of a traditional electromagnetic type current transformer and a photoelectric type current transformer. With the intelligent transformer substation current transformer polarity testing device adopted, polarity test wiring and test working load of an intelligent transformer substation current transformer can be greatly reduced. The intelligent tr
