摘　　要：论述磁位计的工作原理并通过实验对其可行性进行了验证 ,证明并指出磁位计以其线性好、反应速度快、无磁饱和、体积小、重量轻等特点 ,有可能成为新一代数字化继电保护用电流互感器。In order to solve the magnetic saturation problem of traditional current transform ers used in protective relaying,a new type of current transformer,that is magnetic potentiom eter,is proposed.Its principle is dissertated from theories and validated by experiments.It is proved out from the results of experim ents that magnetic potentiom eter m ay become the im portant part of new generation of current transform ers for digitalization of protective relaying for its good linearity,fast response,having no magnetic saturation,being sm all in volume and light in weight.
