The invention discloses a method for evaluating residual magnetism of current transformers for measurement. The method comprises the steps that according to a secondary recorded diagram of an electrictransmission line, a current end corner and a short-circuit current effective value are obtained when a short-circuit fault occurs; a magnetic flux value of a saturation magnetic flux point and a voltage value of a saturation voltage point are obtained by using a basic magnetization curve; residual magnetism coefficients of the current transformers and impedance of a secondary load are pre-obtained; according to the current end corner, the short-circuit current effective value, the magnetic flux value of the saturation magnetic flux point, the voltage value of the saturation voltage point, the residual magnetism coefficients of the current transformers and the impedance of the secondary load, the residual magnetism of the current transformer in each phase of the three phases is respectively calculated; the residual magnetism weight coefficients of the current transformers of the three phases are respectively calculated; and according to the residual magnetism of the current transformers of the three phases and the residual magnetism weight coefficients of the current transformers of the three phases, the residual magnetism of the current transformers is calculated.
