The input at sending end, irrespective of corona loss, is 3,000 kw. Hence 

 approximately 



2,750 



'I = 



3,000 + 2,120 



•537. 



Thus the efficiency is greatly reduced by corona. 



Here the loss from tlie line due to corona discharge is so great that the value 

 of the leakage conductance /if chosen abo\'e must be increased if a better deter- 

 mination of the performance of the line be required. 



If so high a voltage as 132,000 be desired, it would be necessary to use a 

 conductor of larger diameter for the sake of reducing the corona loss. Possibly 

 aluminium might be employed instead of copper. *
