| Abstract: | The mal -operation of the current transformer (CT) caused by super - saturation when badly mal-functions occur is analyzed in details by combining with the practical cases, and the testing method of error 10% for simple CT is put forward, which is worth referencing to avoid the protective mal -operation of CT re-sulted from super - saturation in the paper. |

| Keywords: | relay protection current transformer saturation characteristic measure method measure error |
