FORMULAS FOR SHORT LINES 21 



(5) K.W. at receiver end = -- (FP 8 - GQ a ). 



(6) Power factor at receiver end = 



/ K.v.A. 



V + *F] 



(7) In-phase current at receiver end = * -^^ in total amperes.* 



(in decimals). 



* 



F -4- 



(8) Reactive or quadrature current at receiver end 



in total amperes.* 



When this quantity is positive, the current is lagging. 

 When this quantity is negative, the current is leading. 



(9) K.W. loss in line = (E S P 8 - FP S + GQ.). 



(10) Per cent efficiency of line = pe r cent. 



-C-3-C 8 



Total amps. 



* Amperes per wire, three phase, = - -7= -- 



V 3 



Total amps. 

 Amperes per wire, two phase, = - -
