| Abstract: | After introducing two confirming sampling reference methods, manual setting and automatic confirmation,a new automatic confirmation method based on data channel is put forward, and a realizing approach is detailed. This method has been utilized in digital optical fiber current differential protection, and has proved to be simple,practical and reliable. |
