-Q2) A 25 KW ,250VV ,1800RPM ,shunt DC generator has the following parameters :- RA-0.22; Rsh= 502; Radj=0-1502 Nsh =2500 turns per pole, FAR= 500 A.turns ,and the magnetization curve is shown in fig.(2). Find :- a) If this generator at no-load condition, what is the range generated voltage can be achieved ? b) If Radj=50 2; Find :- the generated and terminal voltages (Ea;Vr)at no-load and at full load with out armature reaction and with armature reaction c) If the terminal voltages (Vr) was found to be 200 V What would be the armature current equal. And haw much field current be flowing in the generator and how much the generated voltage (EA) d)If the speed of the generator decreased to the1500 RPM, haw much the generated voltage (EA) d) find the maximum load current(Iax) the critical resistance (Rc) and the steady state short circuit current -Q2) A 25 KW ,250VV ,1800RPM ,shunt DC generator has the following parameters :- RA-0.22; Rsh= 502; Radj=0-1502 Nsh =2500 turns per pole, FAR= 500 A.turns ,and the magnetization curve is shown in fig.(2).
