Split Core Current Transformer, 20A AC, 10mm

Dimension Unit (mm)

Q1: What is a split-core current transformer?
A1: Split core current transformer is made of high strength PVC shell, fully cast busbar type structure. a split core current transformer is directly stuck on the cable with three sexual rubber rings against the cable and the cable one. The transformer core uses better silicon steel rolled, the secondary wire evenly wound in the core. Transformers for the open and closed structures can be installed without cutting the cable.

Q2: What is the meaning of the circles of the split core current transformer?
A2: On electrical system diagrams, a small circle is often used to represent a winding, and a circle is used to represent a winding. If you have two circles in a series, that means that the open and closed current transformer has two windings. If you have three circles in a series, that means you have three windings.

Q3: What is a split core current transformer error?
A3: Due to the structure of the split core current transformer core and material properties, the current transformer has an excitation current I0, which makes it produces errors.

Tips: Notes for installation of split core current transformer

1. Construction according to the drawings, wiring correct, both ends of the line number label should be clear, label range in line with the requirements.
2. Current and voltage circuits should be grounded at the outlet of the transformer's secondary side. The voltage circuit should be protected by a fuse.
3. The secondary return line of the panel cabinet should be free of connectors and the middle of the control cable or line should be free of connectors. If there is a connector, it should be connected through its long junction box.
4. The secondary circuit of the split core current transformer should have good insulation to the ground, and there should be no mixing of the voltage circuit and current circuit.
5. The secondary circuit wiring should be arranged neatly and beautifully, and the connection screws between the wiring and electrical components and junction box should be free of false looseness. The distance between the wiring tying points should meet the requirements.
6. The cycle can not be reversed, phase sequence and phase difference should meet the requirements of the design and regulations. For transformer wiring with differential protection, the phase diagram of the two arms must be measured before putting it into operation to check the correctness of the wiring.
7. Secondary circuit wire or cable should be used copper wire. split core current transformer circuit cross section shall not be less than 1.5mm. outlet junction box shall be selected with special current terminals. split core current transformer unused secondary winding shall be short-circuited and grounded on the terminal block.
