THE REGULATION OF TRANSFORME1 105 



For the example we are employing, this occurs for G = 0, 1 1. 

 For still lower power factors of the external secondary circuit, 

 the pressure drop again decreases, as will be seen by a study 

 ;:', and ', L the latter representing the limiting case of 

 90 lag. In Fig. 65 the values of the drop are plotted in two 

 c . lirv es i n the one the drop is plotted as a function of the power
