flow of free eletrons through a conductor by means of
potential difference(voltage) in a direction from +ve
terminal to _ve terminal becoz lower potntial to higher
potential

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.
