This paper not only expatiates on the damage of remanent in CT core but also explains the causations and approachs of the remanent established. Follow on,it analyzes the effects on measuring CT and protective CT in theoretically. The effects of remanent in CT core are also validated by test and citing outcomes of the test.Finally,the paper puts forward some practicable solutions.
