Tips: What is transformer load operation?
The load operation of the transformer refers to the working condition when the original winding is connected to the power supply voltage and the auxiliary winding is connected to the load. At this time, the secondary side of the transformer also has current flowing, and the access circuit of the original transformer increases correspondingly compared with no-load, and the secondary side voltage will be affected by the load and change.
