摘　　要：标积制动式差动继电器的改进型特性用常规比率差动继电器也一样可以获得。重要的是根据故障特征整定继电器的参数,既保证区外故障时的选择性,又在区内故障时获得足够的灵敏度。Characteristic of the improved scalar product restraint differentrial relay can also be obtained by ordinary ratio differential relay. It is important to set the parameters of the relay according to the fault characteristics. Thus the relay will get selectivity and sensitivity.
