What is meant by line losses, how do you prevent the losses?
Answer Posted / sk sazzadur rahaman
Line loss means loss due to I2R effect. That is the heating
loss in the transmission line. It is equal to Current
square multiply by resistance of total line.
It can be reduced by reducing the resistance of the line
ie. by increasing the diameter of wire. Or by sending the
same wattage, reduce current and proportionally increase
the voltage.

why do you add the load short circuit impedance when considering short circuit amperage. It seems that you should only consider supply. If you need to consider loads and you don't know what loads are to be added , what would be a good sub-transient reactance rating for the loads?
