- Current transformers are nonreplaceable in the field of protection and measurement for decades , but the electromagnetic current transformers can not meet the development of the electric power system for the reasons of magnetic saturation , ferro resonance , little dynamic range , narrow service band and so on 。 with the popularization of microcompute , it will be irreversible to apply microcompute in the protection and measurement , the equipments do not need the current transformer with high power , so the rogowski coil can apply on the field of protection and measurement
电流互感器在继电保护和电流测量中的作用长期以来具有不可替代的地位，但电磁式电流互感器所固有的磁饱和、铁磁谐振、动态范围小、使用频带窄等都难以满足电力系统发展的要求。随着微机的普及，在继电保护和测量中应用微机已是不可逆转的潮流，设备已不再需要高功率输出的电流互感器，因此可以选用rogowski线圈作为低电压输出要求的电流测量和继电保护应用。
