2.The working principle of split core current transformer
The working principle of the open-ended low-voltage current transformer, the primary winding of the open-ended current transformer is connected in series in the line under test, I 1 is the line current, that is, the primary current of the current transformer, the primary turns of the current transformer, and the secondary current of the current transformer. Current (usually 5 A, 1 A), N 2 is the secondary turns of the current transformer, which is the impedance of the secondary circuit equipment and connecting wires.
