A. Primary winding
B. Secondary winding
C. High voltage winding
D. Any of the above
Answer: C. High voltage winding
Explanation:
Tapings are connected to the high voltage winding side, because of low current. If we connect tapings to the low voltage side, sparks will produce due to high current.
The number of turns in the High voltage winging is large and hence a fine voltage variation can be obtained.
LV winding is placed nearer to the core and HV winding is placed outside.
Therefore providing taps on the HV winding is comparatively easier than that of the LV winding.
