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.
