In a transmission line, if a booster transformer are to be used, preferred location will be:

  • A.At the receiving end
  • B.At the sending end
  • C.At the intermediate point
  • D.Anywhere in the line

Answer: C

The preferred location is At the intermediate point.

A booster transformer corrects the voltage drop along a line. Placed at an intermediate point it lifts the voltage where the drop has become significant, so consumers on the far part of the line receive close to normal voltage while the near part is not over-boosted.

At the sending end the boost would be applied where the voltage is already highest. At the receiving end the consumers along the line would see no benefit. The location is chosen from the voltage profile, so 'Anywhere in the line' is wrong.
