| Abstract: | The paper proposes some self_adapting schemes to complete the functions of CT scale coefficients adjusting and CT polarity checking and correcting in transformer longitudinal differential protection, which makes micro-computer based protective relays more intelligent and can accomplish these works to be done automatically. And two draft resolutions were proposed trying to solve the problem of CT polarity checking in transformer zero-sequence differential protection. |

| Keywords: | transformer longitudinal differential protection zero-sequence differential protection self_adaption |
