Coupling factor for current sense transformers

[treez]

What do you think would be the coupling factor for these current sense transformers?

Hi,


do you mean I(sec) / I(prim)? --> = n(prim) / n(sec): look at the "turns ratio".

thanks but no I am speaking of the leakage inductance

Hi,

Ok i see what you mean.

No idea about the value, sorry.
