Answer / koti
It is not primary, but HV side. For OLTC-above answer of
low current is OK. For Off-Ckt TC; more turns to get more taps, away from core i.e. near to tank which facilitate easy tap connections.

Answer / raju
Tapings are connected to high voltage winding side, because of low current. If we connect tapings to low voltage side, sparks will produce while tap changing operation due to high current.

Answer / renato elamne
_we used a tapchanger in the transformer so that we can select a tapping,same voltages to the primary lines input to the transformer..exam..if 17627 volts primary lines,the tapchanger also point to 17627 taps.

Answer / bhabanipattanayak
In a transformer pri. Wdg. Is
always wound over sec. Wdg.
So it is not possible to
connect tap changer in sec.
Side. For this reason we use
tap changer in pri. Side.

in a 740 kw dc seperately excited motor field voltage is constant about 17.4 volts and armature voltage is500 volts dc. how it is possible to have two different voltages from single transformer of output voltage 500 volts? if any difficulty in question contact ajitsingh.kadian@gmail.com
i want to ask that as everybody knows that in star connection on star point is called neutral. my question is that why on that poin called neutral. what is the reason behind it. what is the logic behind it. i heared somewhere that on this point all phases current become zero thats why. if this answer is right then prove why on that point is current become zero. if this answer is not right then tell me the right answer. post ur answer here or on my mail address. m.ikram786@yahoo.com m.ikram555@gmail.com. thanks.
