Yes. As I said, the primary is often just the power wire running through the center of the core.Both secondary and primary coils are wound on the same magnetic (toroidal) core?
It doesn't make sense to me.
Of course the turns ratio has meaning. The voltage on a winding is the flux through the winding times the number of turns. Since windings wound on the same core, share the same flux, then their relative voltage is equal to the turns ratio.Hi.
If they are wound on the same core, then the turns ratio has no meaning.
I mean that in that case, only N(Secondary) counts and sets I(Secondary), and not
N(Primary) / N(Secondary).
Hi Ron,
Thanks so much for this detailed post.
I got you know.
So actually the CT - as it comes out of the factory - contains only a Seconday Winding which is wound on its magnetic core, right?
And the Primary Winding is considered to be the Current Carrying Wire (such as, Live wire of an household), right?
