The voltmeter is equal to the accurate measurement equipment for the large load (large impedance) of the voltage transformer. The ammeter is equal to the current transformer’s small load (small impedance) accurate measurement equipment.
In the normal operation of the voltage transformer, the secondary load impedance will be very large, the voltage transformer is a constant voltage source, the internal impedance is not large, the capacity is not large, the primary winding transmission line is very thin, when the transformer short-circuit fault occurs twice The primary current will be very large. If the secondary fuse is not selected properly and the fuse cannot be fused, it will cause the voltage transformer to be easily burned.
When the secondary side of the current transformer is open during operation, the primary side current will not change. The secondary side current is equal to zero, and the demagnetizing flux caused by the secondary current will also disappear.
