Hi, Just made a small thought experiment on the train, haven't really thought about it in depth. I was just wondering, if I created the above scenario (open circuit secondary and a voltmeter), would I get a voltage (assuming there is a difference in turns for primary and secondary)? Neglecting like capacitive or inductive coupling.
I have a feeling not, because both sides are isolated. (?)
And if so, could this be used to tell me something about the turns ratio or it's error?
Presumably if there was a voltage, both sides of the TX would be in-phase. But, please remind me, if the sides were slightly out of phase, that would be from the resistance in the primary and secondary coils?
So say the phase of the secondary was a bit out from that of the input, what would that mean to the 'class' of the transformer?
Also, would you then need like a bridge to feed in the primary and secondary to see the phase error of the TX?
Or what if the turns ratio is like N decimal point something? (not exactly just N) what does that mean for the TX 'class'?
