I got a few questions about transformers..
I understand there is a primary winding and secondary winding wraped around a iron core.
Now for the primary connection - take 7.2kv 1 phase line and connect it to one side of the winding and take ground (earth) to the other winding end.
On the secondary winding if the windings are set up right by amount of turns i can get 240 volts correct. -120v one line and +120v on the other
If i connect a wire in the center of the secondary winding the voltage would be 0 here? and i get 120 between center tap and line? connecting the middle of the winding to ground is just for protection? ( just making sure that the connection from the middle of the winding to ground is what's making it get 120)
