The proportion of this furnished by Station No. 1 and Station 

 No. 2 may be found as follows :

Station No. 2: 



X 233,000 = 84.000 Kv.A. 



In like manner the proportion of this Kv.A. that flows over 

 each individual portion of the circuit may be readily determined. 



In certain cases a system may consist of such a complex net- 

 work of lines so as to make the calculations exceedingly difficult 

 and the results consequently more or less uncertain. To aid in 

 the solution of problems of this nature, an electrical device has
