Please try go get the basics down. You should have learned this in school.

The OLTC (online tap changer) is installed on the high voltage side.

For second part of your question, I would like you to think and find the answer.

Although it is a bit specialized, this could be a reasonable monthly challenge question.

Dear Mr.msamad,

I am of the opinion - after having told the reason, for 1st half question, we should reply the "WHY" part of the question.

I think with your permission, I can reply as

"ON THE HIGH VOLTAGE SIDE - THE CURRENT WILL BE LESS TO THE EXTENT OF RATIO OF N2/N1, and THE DAMAGE ON ACCOUNT OF ARCING WILL BE MINIMUM"

THANKS,

DHAYANANHAN.S

Is it an interview question or one came in your exam? Better study the fundamentals . If you read any basic book on transformers you could clear your doubts . Better start with your fundamentals before putting questions in this forum.
