What are the installation requirements for split core current transformers?

When the split core current transformer is operating normally, everyone should stop the device according to the technical requirements such as the specification book. To be more clear, let's take a look at this.

1. The split-type current transformer is constructed according to the drawings, the wiring is correct, the wire number labels at both ends are clear, and the label range meets the requirements.

2. The current and voltage circuits should be grounded at the secondary side outlet of the transformer. The voltage circuit should be maintained with a fuse.

3. The secondary circuit of the panel cabinet should not have a connector, and there should be no connector in the middle of the control cable or line. If there is a connector, it should be connected through its long junction box.

4. The secondary circuit of the split-type current transformer should be well insulated from the ground, and the voltage circuit and the current circuit should not be mixed.

5. The wiring of the secondary circuit should be arranged evenly and beautifully, and the connecting screws of the wiring and electrical components and junction boxes should not be loose. The spacing between the wiring binding points should meet the requirements.

6. The cycle cannot be reversed, and the phase sequence and phase difference should meet the design and specification requirements. For the transformer wiring with differential maintenance, it is necessary to measure the phasor diagram of the two arms before putting it into operation to check the correctness of the wiring.

7. Copper wire should be used for the secondary circuit conductor or cable. The cross section of the voltage transformer loop shall not be less than 1.5mm. Special current terminals should be selected for the socket junction box. The unused secondary winding of the transformer should be short-circuited and grounded on the terminal board.

The above are the requirements that should be followed when installing the split-type current transformer. In order to ensure normal operation and prevent future problems, everyone needs to follow the correct installation steps when installing. While meeting their technical requirements, we hope to deepen everyone's understanding of the product.
