A current detection system, a current detection method, and a detection apparatus are provided. The current detection system includes a printed circuit board and N groups of amplification apparatuses, wherein N is a positive integer greater than or equal to 1. Each group includes at least one amplification apparatus. N Rogowski coils are mounted on the printed circuit board. The nRogowski coil is capable of being mounted concentric with the ncurrent-carrying conductor in N current-carrying conductors, which is perpendicular to a plane of the nRogowski coil. An output end of the nRogowski coil is connected to an input end of the first amplification apparatus in the ngroup of the N groups of amplification apparatuses. The foregoing current detection system provides more convenience when being integrated into different electrical equipment, in particular when each group of amplification apparatus includes multiple amplification apparatuses.
