What’s the purpose of high voltage transmission?
We can see the high voltage tower stand at suburban. The power plant
raises the voltage while generating the power, then downs the voltage
when transmits the power to power station. What’s the purpose of
high voltage transmission do you think? According to the energy
formula, P = V * I, so the current will be reduced while raising the
voltage. Besides, as you know that each cable has the wire impedance.
So, referring to Ohm rule (V = I * R), this decreased current makes the
low power consumption. So the high voltage transmission just for
reducing the power consumption.
