Answer / ranga2k8

strength of cable, it will be made in spiral in shape.One
more reason is we can bend the core whenever a sharp curve
is needed in the erection of cable.

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.
