REACTANCE OF TWO-PHASE AND THREE-PHASE LINES 8l 

 The reactive voltage on conductor A per mile is 

 1.00(80.5 + 741.1 log J/7 2 irf X lo" 6 

 (due to flux from I A ) 



+ (-0.50 +0.8667) (741. 1 logyJ/727T/X lO" 6 



(due to flux from IB) 

 + (-0.50 -0.8667') (741. i logy]// 27T/X iQ" 6 



(due to flux from /c), 



where p is the radius of the wire. 

 The reactive voltage on conductor B per mile is 



1.00(741.1 log J/7 2 TT/ X iQ- 6 



(due to flux from I A ) 

 + (-0.50+0.8667)^80.5 + 741. i log ^//^Tr/Xio- 6 



(due to flux from IB) 

 + (- 0.50 - 0.8667) (741.1 log J Ij 2 TT/ X iQ- 6 



(due to flux from /c). 



The reactive voltage between A and B is therefore 

 (1.50 0.8667) (80.5 + 741.1 log-) Ij 2 irf X IQ- 6 



+ (0.50 + 0.8667) 741. 1 (log log-)//27T/X IQ- 6 .

Suppose at the end of one mile the line is transposed 

 so that the above two conductors occupy the positions B
