Tips: The difference between no-load and load transformer
The main difference between no-load operation and load operation of the transformer is mainly reflected in the secondary line state. The secondary line of the transformer load operation is connected to the load, and the generated power is large.
The transformer uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). In electrical equipment and wireless circuits, it is often used for voltage rise and fall, impedance matching, and safety isolation. When the transformer is running at no load; only no-load loss, that is, iron loss and stray, is consumed, which is 6% of the total capacity, and when the load is running, it is no-load loss + load loss, that is, copper loss, which is the total consumption of the transformer.
