经过一个电流互感器测量单相电流的电路
Circuit for Measuring Single Phase Current through a Current Transformer
在交流电路中，如果被测电流较大，或者被测量电路的电压较高，都可以使用电流互感器和量程为5A的交流电流表测量电流，这是为了扩大电流表量程，同时也比较安全。电路的接线如下图所示，左边的是平常我们使用交流电流表的测量电路，直接串联负载进行测量，右边是需要用到电流互感器时的电流测量电路图。
In AC circuit, if the measured current is large or the voltage of the measured circuit is high, the current can be measured by current transformer and an AC ammeter with a measuring range of 5A. This is in order to expand the measuring range of the ammeter and is also relatively safe. The wiring of the circuit is shown in the following figure. On the left side, we usually use the measuring circuit of the AC current meter to measure the load directly in series. On the right side, we use the current measuring circuit when the current transformer is needed.

使用电流互感器测量时应注意：
When using the current transformer to measure, attention should be paid to:
互感器二次侧不允许开路，因此，二次侧不能安装熔断器和串联开关。
No open circuit is allowed on the secondary side of transformer, so fuses and series switches can not be installed on the secondary side.
为了安全二次绕组的一端必须可靠接地。
In order to be safe, one end of the secondary winding must be grounded reliably.
