    Split core current transformer current transformers are not allowed to be used in open circuit, and cannot be connected to a fuse. When using, be sure to first connect the transformer output load device, otherwise the output generated by the open circuit voltage will have an incalculable impact on personal safety.

    Tips: Current ratio of current transformer

    The current ratio of the primary winding current I1 to the secondary winding I2 of the current transformer is called the actual current ratio K. The current ratio of the current transformer when it works at the rated current is called the rated current ratio of the current transformer, expressed by Kn, Kn=I1n/I2n

    The polarity of the current transformer is generally marked by the principle of subtractive polarity, that is, the magnetic flux generated by the current in the primary and secondary windings in the iron core is opposite in direction.
