Engineering Do you have to refer core losses in equivalent circuit?

AI Thread Summary
Core losses in a single-phase transformer equivalent circuit should be referred to the secondary side, as they are dependent on the current, which varies between the primary and secondary sides. Referring core losses, represented by Ro and Xm, is essential for accurately modeling the transformer's behavior. This practice not only enhances the understanding of the system but also addresses non-ideal effects in the transformer operation. Including these losses in a lab report demonstrates a comprehensive grasp of transformer dynamics. Properly accounting for core losses is crucial for an accurate equivalent circuit analysis.

Hi, I'm currently writing a lab report on single phase transformers and I need to determine the equivalent circuit with respect to the secondary side. I have already found the parameters with respect to the primary side so it is just a matter of referring them to the secondary side. What I would like to know is whether the core losses (Ro and (Xm) have to be referred as well and why.

I think they should be referred because they are a function of the current which would change depending on if it's in the primary or secondary side...right? :confused:
However, I'm not 100% sure so can someone tell me if I'm right or wrong in thinking this way please?

Thanks in advance :smile:

core losses xm and ro can be modeled as a resistor and an inductor both in parallel with the primary coil.

In a lab report it would be very good to refer to them as it would demonstrate understanding of the system as well as an understand of non ideal effects.
