QDC CT is using to manage the AVR according to load change. SCM CT is using to manage the excitation energy requirement during short circuit.

Answer / r p pandey

SCM ct are connected in field exciter circuit through SCM bridge, when high current encrease in main circuit then it protect our generator by controling excitation.

Answer / hitesh gavaniya

SCM CT is a normal ct , which is connected with generator output terminal , and CT's Terminal are connected with AVR . Depending on the load on the generator , the current increases & Accordingly SCM CT gives the input to the AVR so as to develop the required field to generate the same load without any dip in the voltage.
