Figure  2.4.2  presents  the 

control  diagram  of  the  voltage 

regulators  GRT7-TH4  E/PE. 

The  control  is  based  on  the 

ST1A,  presented  by  IEEE, 

applied  to  systems  where  the 

rectifier  is  supplied  from  the 

generator  output  (Type  ST  – 

Static  Excitation  Systems), 

whether  directly,  by  auxiliary 

coils or transformer.
