| Abstract: | The problem of synchronous current sampling at all terminals of the line is the key technique in carrying out digital current differential protection. Several synchronization processing methods in common use and newly proposed ones are described in detail in this paper. Both features and shortcomings about these methods are analyzed and compared each other. |
