TABLE III 



Formulas for Long Constant-Voltage Lines. 



Conditions Given at Receiver End. 

 These formulas give the results of the fundamental 

 hyperbolic formulas as accurately as desired, if a suf- 

 ficient number of terms of the convergent series is used. 



Conditions Given: 

 E Voltage at receiver end. 

 E 8 = Voltage at supply end. 

 Z =R+jX. 



R = Resistance of one conductor. 

 X = Reactance of one conductor. 

 F =G+jB 



G = Leakage conductance of one conductor. 

 B = Capacity susceptance of one conductor. 



(See Tables VII-XVI, "Transmission Line 



Formulas.") 



P = In-phase current of the load, in total amperes. 

 cos 8 = Power-factor, lagging, of the load.
