At this time, the primary current becomes the excitation current, which saturates the transformer core and the magnetic flux is also very high, which will cause the following adverse effects:

(1) Because the magnetic flux is saturated, its secondary side will cause a high voltage of thousands of volts, and the wave shape changes, causing great harm to personal safety and machinery and equipment.

(2) Because the magnetic flux of the transformer core is saturated, the loss of the transformer core becomes large, resulting in high temperature, which will destroy the insulation layer.

(3) Residual magnetism will be caused in the transformer core, which will enlarge the ratio difference and angle difference of the transformer and lose accuracy. Therefore, the secondary side of the current transformer cannot be opened.
