TRANSFORMERS 

 TABLE XLVII 



411 



* One half of main has capacity of 0.557; other half 0.150; total capacity computed 

 on basis that both halves are alike and of large capacity. 



t On basis of primary capacities when there is a difference between primary and 

 secondary. 



T connection, however, requires specially designed transformers, 

 and the complication of starting taps and switches is a disad- 

 vantage. 



The system requires two transformers of the same impedance, 

 each equipped with two low-voltage windings, connected in such
