Not lame at all! I'll try to cover it with a brief explaination:
This polarity is referring to the relationship[s] between the direction of current flow on a primary winding, the induced flow direction in the core, and the direction of induced current flow on a secondary winding - all at one certain instance [such as above the zero line on a sine wave].
This is considered to be Relative Polarity.
It differs from a Fixed Polarity, which is found on typical straight-line DC sources [such as drycells and Batteries], or on Magnetic Stuff [like Permanent Magnets].
Using the Schematic above, what we are trying to find here is which of the leads should be tagged as "X2" and "X3", so the coils can be properly connected in either Series or Parallel.
***Side note*** If the secondary is to be used as the typical "3 wire" system - tapping into the jumper between the split coils for a Neutral Conductor -, but was setup with polarity as shown in "Fig.2", then each of the L-N circuits would be able to function correctly, however the L-L circuit would not function properly.
Kind'a cool, isn't it???
Sure hope this makes some sense!!!
P.S. - Are these Schematics of any help, interest, or benifits to anyone???
Do they need more information or better drawn symbols???
Basically what I am getting at is what everyone thinks of the Schematics, plus any input or suggestions you might have.
If you would like to see a certain schematic posted here, let me know!
