The utility model discloses a test apparatus for the polarity of a current transformer. The test apparatus includes a housing. A current transformer polarity test circuit is arranged in the housing, and is formed by a power supply unit and a plurality of polarity test units. Each polarity test unit is formed by series connection among a current polarity determination and selection unit, an anti-interference and comparison unit and a polarity display unit. Output signals of a current transformer are input to the current polarity verification and selection units for polarity determination, polarity signals that have been determined are denoised and amplified by the anti-interference and comparison units, and finally a polarity determination result is displayed on the polarity display units. The power supply unit provides power to the current polarity determination and selection units, the anti-interference and comparison units and the polarity display units.
