Then why do transmission voltage is kept high? Is it not counter intuitive that higher the voltage higher will be the power loss.

Question

Accepted Answer

Transmission voltage is kept high to reduce power loss over long distances.

Higher voltage reduces current, which in turn reduces power loss in transmission lines.
High voltage allows for efficient long-distance transmission without significant power loss.
Step-up transformers increase voltage for transmission, while step-down transformers decrease voltage for distribution.
Power loss is proportional to the square of the current, so reducing current by increasing voltage helps minimize losses.

Accepted Answer

No, for a give power higher the voltage lower will be the current. Lower the current lower will be the I2 R loss. Hence, higher transmission voltages make the transmission system very efficient.
