| description | A method for evaluating the residual magnetism performance of a 10-110kV current transformer relates to the technical field of current transformer residual magnetism evaluation, and is structurally characterized in that the main object of a current transformer residual magnetism performance evaluation system is iron core residual magnetism, the variable quantity of the magnetic flux in an iron core is obtained by utilizing a voltage integration method according to the relation between the current transformer induction voltage and the magnetic flux through split-phase evaluation, and the variable quantity of the magnetic flux in the iron core is calculated. The overall evaluation comprises a three-phase short-circuit residual magnetism evaluation method, a two-phase short-circuit residual magnetism evaluation method and a single-phase short-circuit residual magnetism evaluation method, and the current transformer can be divided into a normal state, an attention state and an abnormal state according to the magn |
