why is HV transmission economical?
HV transmission economical?|
Voltage times Current. Sending at domestic voltage requires much more current
to be sent for the same power and therefore much thicker wires, heavier
equipment and more repeater transformers as over distance the resistance of
the wires and switches would cause the voltage to fall quickly below
domestic. For the same power delivery, sending at higher voltages requires
less current, lighter wires, and voltage losses over distance are more easily
managed so much less equipment is required.|
