Current transformer detection system and method

The invention discloses a current transformer detection system and method, and relates to the technical field of current transformer detection, the current transformer detection system comprises a current acquisition sensor, a compensation device and a controller, the current acquisition sensor is arranged between a to-be-detected current transformer and a load, and the current acquisition sensor is used for acquiring load current; the compensation device is connected with a current transformer to be detected in parallel, and the controller is connected with the current acquisition sensor and the compensation device; and the controller is used for controlling the compensation device to generate compensation current according to the load current acquired by the current acquisition sensor, so that the current flowing through the to-be-detected current transformer is changed between 5% and 120% of rated current, and the performance detection of multiple current data points of the to-be-detected current transform
