4.Instructions for use:

The split core current transformer is installed online. The input cable passes through the middle hole. After passing the transformer, the secondary output current signal is converted into the required voltage signal by the sampling resistor. Measuring type transformer, the transformer can be directly fixed on the cable with a diameter of 10mm ~ 21mm. This product is installed online without power interruption. All places operated by everyone are insulators, which is convenient, simple and fast to install.
