In case of power or distribution transformer about 10 percent end turns are heavily insulated, this is done so as

  1. To absorb the line surge voltage and save the winding of transformer from damage
  2. To reflect the line surge and save the winding of a transformer from damage
  3. To withstand the high voltage drop due to line surge produced by the shunting capacitance of the end turns
  4. None of above

Correct answer: 3. To withstand the high voltage drop due to line surge produced by the shunting capacitance of the end turns
