MCQ
Using the step up transformer the alternating voltage generated is first stepped up from $X kV$ to Y kV . Regarding this, which of the following is correct?
  • A
    $X =11, Y =220$
  • B
    $X =110, Y =132$
  • C
    $X =110, Y =760$
  • ✓
    $X =11, Y =132$
✓

Answer

Correct option: D.
$X =11, Y =132$
(d)
$X=11, Y=132$
Explanation:
The alternating voltage generated is first stepped up from 11 kV to 132 kV . After that at the sub-station, using the step-down transformer this 132 kV is reduced to 33 kV . Similarly this again in the same manner it is reduced to 11 kV , then 220 V and finally reaches to the consumer households.
