Core volume of 1 phase transformer

AI Thread Summary
The discussion revolves around calculating the core volume of a single-phase transformer using flux density (B) and flux (Φ). It suggests that the core volume can be derived from the formula volume = 4 * cross-sectional area * height, accounting for common parts. However, there is confusion about the relevance of B and flux, as they are influenced by external electrical excitation and do not directly relate to the core's geometrical volume. Participants seek clarification on the term "limb" and its representation in diagrams. The method proposed for calculating core volume is questioned, emphasizing the need for a clearer understanding of the relationship between these parameters.

Homework Statement


The flux density in a single phase core type symmetric(length=breadth=height) transformer is B and flux is Φ. Can we find out the volume of core of transformer if the height of limb is h?

Homework Equations


Φ = B * Cross sectional area

The Attempt at a Solution


Can we say that the volume of core = 4*Cross sectional area*h - Common parts(refer the file uploaded)

If you will explain what you mean by "limb" that would help. Show a "limb" on your diagram?
And what is the point of mentioning B or flux?

you can refer the below image for reference. I have mentioned flux and flux density because from these two we can find cross sectional area and with the formula i mentioned above we can find the volume of core.

Is this the right method to get value of volume of core?

B and flux depend on externally applied electrical excitation and have nothing to do with core volume or other geometrical aspects.

If we have flux and flux density as the only parameters and we are suppose to find the core volume, will the above method be right?

Thanks for the answer.
