Tips: What is no-load operation of a transformer?

The no-load operation of the transformer refers to the working state in which the primary winding of the transformer is connected to the power supply and the secondary winding is open. At this time, the current in the primary winding is called the no-load current of the transformer. No-load current generates a no-load magnetic field. Under the action of the main magnetic field (ie, the magnetic field that cross-links the primary and secondary windings at the same time), an electromotive force is induced in the primary and secondary windings. When the transformer is running at no load, although the secondary side has no power output, the primary side still draws part of the active power from the grid to compensate for the hysteresis loss and eddy current loss caused by the magnetic flux saturation in the iron core | . The size of the hysteresis loss depends on the frequency of the power supply and the area of the hysteresis loop of the core material; the eddy current loss is proportional to the maximum magnetic flux density and the square of the frequency. In addition, there is copper loss caused by no-load current. For transformers of different capacities, the size of no-load current and no-load loss are different.
