Answer Posted / tse-wang
All answers are correct and more closely the answer No.3.
However, i am not comfortable with the fuction of the OLTC
described here in the forum:
The function of the OLTC (On-load-tap-changer) is to
maintain/regulate the output voltage of the transformer.
(This is general answer).
Technically, we are trying to change the winding turns
ratio (N2/N1) to change the mutual induction between the
two (or may be 3) windings.
