Current transformers are a measuring transformer used to measure the current. With the current transformers, the current passing through the electrical line is reduced to a certain value and transmitted to the measuring instruments. Instead of directly connecting the measuring tools to the electrical line, the reason why the current transformers are reduced to smaller values ​​is that the measuring instruments cannot measure these high current values, so the current should be reduced to a certain rate and then transmitted to the measuring instruments.

Current transformers passing through the cable/bar current transformer in the order of the translation rate by reducing the detection through the secondary terminals to the device.

In order to provide a precise measurement through the current transformer, it is important to measure the current transformer correctly.
