The uses, operating principle and main requirements of the currenttransformer for differential relay with high impedance were described.
叙述了高阻差动继电器用电流互感器的用途、工作原理和主要要求。

The transformation ratio of the original currenttransformer (CT) on the transformer HV side was so large that a parameter for the differential protection software exceeded its settable scope.
因变压器高压侧的电流互感器选择变比过大,以致超出差动保护软件的参数设置的范围。
