2 Answers Bharat ITI,

At 765Kv, I have seen the use of PT at line side for metering and CVT for protection, although as far as my knowledge is concern, PT at this voltage level will have huge loss and more cost as compared to CVT as CVT can also perform same function of Protection and Metering? So my question is why use PT and not CVT for metering and protection in order to reduce the cost.
