Fill in the blank: The no-load current of a transformer refers to ( ). Answer: The secondary side is open-circuited, with some current flowing in the primary side
Open circuit in the secondary measurement; some current present in the primary measurement
The percentage of the excitation current when the transformer is operating under no-load conditions relative to the rated current.
Open circuit in the secondary measurement; some current present in the primary measurement

Open circuit in the secondary measurement; some current present in the primary measurement
When the secondary side of the transformer is open-circuited, the current flowing through the primary coil is the no-load current.
The primary side is connected to the rated voltage; the primary current measured with the secondary side completely unloaded
When the secondary of a transformer is open-circuited, there is still a certain amount of current in the primary; this current is known as no-load current
When the secondary side of a transformer is open-circuited, and a rated voltage at the rated frequency is applied to the primary winding, the current flowing in the primary winding is called no-load current.
