Electrical Current Transformer function

- Nov 30, 2020-

Similar to the transformer, the Electrical Current Transformer also works according to the principle of electromagnetic induction. The transformer transforms the voltage and the Electrical Current Transformer transforms the current. The winding (the number of turns is N1) connected to the measured current is called the primary winding (or primary winding, primary winding); the winding (the number of turns is N2) connected to the measuring instrument is called the secondary winding (or secondary winding) Winding, secondary winding).

The electrical current transformer primary winding current I1 and the secondary winding I2 current ratio, called the actual current ratio K. The current ratio of the Electrical Current Transformer when it works at the rated current is called the Electrical Current Transformer rated current ratio, which is represented by Kn.
