摘　　要：讨论了数字式比率差动继电器的两种通用比率制动判据及其特性，并分析了此通用特性在输电线路差动保护、变压器差动保护、母线差动保护及发电机差动保护中的应用性能。采用此通用特性可以不必进行保护的整定计算，使保护的使用非常方便。Two general restraint criteria and their characteristics of the digital percentage differential relay are introduced. The applications of the general characteristics to the transmission line differential protection, power transformer differential protection,bus differential protection and generator differential protection are discussed, With the general characteristics, the calculation for relay setting is not necessary.
