PHASE DIFFERENCE OF CONDENSERS

of course, fall exactly upon the line of observed values and the 
discrepancy is to be attributed to the fact that the phase differ- 
ence of the condensers has not been taken into account.

Fig. 19. — ^Vector diagram assuming known phase difference. 
If we assume that the phase difference e is known and con- 
struct the vector diagram, figure 19 will he the result. The angle 
^ determines the slope of the line On along which fall the 
vectors representing the different values of the condenser cur-
