The invention discloses a self-healing optical current transformer, which relates to a current transformer and is disclosed so as to solve the problems that a traditional optical current transformer has low measurement accuracy, low temperature stability and low reliability after running for a long time. An optical current sensor and a self-healing corrector are arranged on an electric power transmission bus; the data signal output ends of the optical current sensor and the self-healing corrector are respectively connected with the data signal input ends of a digital signal demodulation module and a power frequency filtering module in an algorithm realizing unit; the signal output end of the digital signal demodulation module is respectively connected with the signal input ends of the power frequency filtering module and a factor correction module; and the data signal input end and the data signal output end of a fault judgment module are respectively connected with the data signal output end of the power frequency filtering module and the data signal input end of the factor correction module. The self-healing optical current transformer has the advantages of high measurement accuracy, high temperature stability and high reliability.
