Core Loss Calculation - Cylindrical Transformer

06/25/2010 5:48 AM

can i solve for core loss of a cylindrical transformer by knowing the dimensions of it and the material it is made of?

What is a CYLINDRICAL TRANSFORMER?

That link is so cool!

I predict that it will become a hit here.

If you can measure what goes in and what comes out, including temperature rise, you can get a rough idea of the core loss.

i know that, but i dont want to build a transformer, i want to know what kind of loss there will be before i build it.

i found the equation, but i dont understand the variables.

this is the formula for calculating core loss

alpha, beta and k are constants that have to do with the material of the core. what are f and B, and what exactly does Pcore mean?

Loss will be zero, because you don't want to build it.

so ur saying it is impossible to calculate based on dimentions and voltages etc? u have to build it and experiment? are u sure it is impossible?
