What is the SN on the transformer? What is the difference between it and the actual power of the transformer?
Corresponding to the line of fire and the zero line, there is a L is the ground
The unit of apparent power SN is kVA,
"Transformer's actual power" is said that active power, right? Active power PN = SN * power factor, in kW
What you say SN is the rated capacity of the transformer, the capacity is also called the apparent power. It represents the maximum power that the transformer can transmit in the rated state, that is, the maximum power that the transformer can transmit when the power factor is 1 is SN kW.
Transformers are only used to transmit power, in addition to their own no-load loss and load loss, the power does not consume. The actual power it delivers depends on the load.

Transformer: Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). In electrical equipment and wireless circuits, commonly used as lifting voltage, matching impedance, safety isolation and so on. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the use can be divided into: distribution transformers, power transformers, sealed transformers, modular transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric transformers, rectifier transformers.
