Question 5
In a 3 - ϕ semi-converter, if firing angle is less than or equal to 60°, then the duration of conduction of each thyristor and diode would be respectively.
Question 6
A divide by 78 counter can be realized by using
Question 7
Two generators rated 100 MW and 200 MW have a governor droop characteristics of 4 % from no load to full load. They are connected in parallel to share a load of 250 MW. The load shared by 200 MW machine is
Question 8
A 5 KW, 200 V, DC shunt motor has armature resistance and field resistance of 1 Ω and 100 Ω respectively. At no load, the motor draws 6 A from 200 V supply and runs at 1000 rpm. What is the total copper losses in the machine?
