| Abstract: | The software revision method of current transformer (CT) for molded case circuit breaker was pre- sented. The CT curves when being low current, no distortion and high current were analyzed. The CT characteristic curves were imitated with Matlab program, and actually measurement and imitational curves were given. Revision result shows that this method with high precision and reliability make design simple in practical application. |
