Bill and Dspark,
Thanks for the reply Q's!!!
1st off, Dspark has pretty much answered the questions better than I can, so I'll avoid confusing things and only add a little bit of information that should have been included with the original schematic post:
These are definitely 1 line schematics. This makes them more like an actual analysis of how things are working, than a graphical representation of the component - such as the typical pictorial symbols.
On the secondary of Fig. 2, the coil s2 is shown on the 1 line to have polarity opposite that of the coil s1.
This is the equivalent to reversing the leads, as Bill was referring to.
So on a pictorial schematic, the coils' leads would be as follows:
[*]X1 would be the lead with the polarity mark on coil s1,
[*]X2 would be the other end of coil s1,
[*]X3 would be the lead with the polarity mark on coil s2,
[*]X4 would be the other end of coil s2.
This diagram shows the relative polarity at fixed points, which will reflect on the connections' "X" numbers.
In a round about way, this will show how and why a reversed connection to the s2 coil will have an effect.
There's nothing wrong with how you are thinking!!! That's the end result we are trying to achieve with this test!!!
Now as to the polarity to the primary input, if we setup the secondaries as shown in Fig.1, then the relative polarity on the primary will be at the opposite corner of the secondary.
In other words, if the secondary coils have rel. polarity established at the uppermost end[s] of the winding[s], then the rel. polarity on the primary would be on the lowermost end[s] of the winding[s].
Does this make sense???
To obtain pri/sec polarity, check out the schematic "Polarity test 2".
Hope this answered the Q's properly.
Thanks for the nice words, too!!!
Also, great reply from Dspark as to Bill's questions.
