Precautions for using split core current transformers, The following points must be noted during use:
1. Before use, it is necessary to check whether the appearance is deformed, otherwise it will affect the testing accuracy.
2. Before use, it is necessary to check whether the end face of the iron core is clean and can be wiped with a dry silk cloth (alcohol and water are strictly prohibited).
3. The usage environment should be far away from strong magnetic fields to avoid affecting the testing accuracy. The usage environment temperature should be between -30 ℃ and+40 ℃, and the relative humidity should be less than 80%. It is strictly prohibited to use in humid and corrosive gas environments.
4. The LZCK and FU series Split core transformer has fastening screws at the opening position. After determining the installation position, please tighten the screws to prevent the transformer from falling off.
5. Polarity
The LZCK and FU series split core transformers have a current flow sign "→" at the label position. The primary current should pass through the transformer in the direction indicated by the arrow (i.e. the arrow head and tail face are "P", and the primary current should pass through the transformer from the "P" face).
6. During use, it is strictly prohibited for the transformer to have a secondary open circuit.
During the installation process of split core transformers, it is necessary to ensure that the secondary circuit is fully connected before installing the transformer to avoid causing a secondary open circuit in the current transformer.
7. The secondary load should not be too large.
When the secondary current of the split core transformer is 5A, the secondary load is 5VA; If the secondary load is greater than 5VA, it will affect the testing accuracy.
8. During use, the end face of the iron core must be kept clean and in a good closed state.
9. During use, it should be handled with care to prevent heavy objects from colliding and affecting accuracy.
10.After use, it must be stored in a clean environment;
